Hi there! I did the big KDE 4.6.3 -> 4.6.4 upgrade. Along came the change to KDEPIM 4.6. I feared for the worst, and indeed, it didn't work too well. On the first login after the upgrade, Akonadi stuff was migrated, and some errors happened. The notice boxes closed automatically before I could make screenshots. Something with the migration of 'Standard-Kalender' to native backend failed, and some more stuff I do not remember. The big problem was that KMail was no longer usable. I got this error: KMail encountered a fatal error and will terminate now. The error was: Failed to fetch the resource collection. Until I closed this notice box, KMail was sort of usable, despite being greyed out. But it crashed when doing things like saving mails as drafts. As I did not have time to investigate this, I switched to Thunderbird for a while. Which has its own problems, like not checking my mail folders for new mail. So yesterday I spent some time to solve this KMail issue. When starting KMail manually, I got this in the output: kmail2(10305)/libakonadi Akonadi::SpecialCollectionsRequestJobPrivate::resourceScanResult: Failed to request resource "akonadi_maildir_resource_3" : "Unknown error. (Failed to fetch the resource collection.)" I did not find this akonadi_maildir_resource_3 in the Akonadi Console. So I grepped through .kde4/share/config/* , and found it as DefaultResourceId in the file 'specialmailcollectionsrc' only. I deleted the file, but it is being recreated identically when Akonadi is restarted. I do not know what this is and where is comes from, but I created a dummy Maildir resource (it was called akonadi_maildir_resource_5), and put that into the specialmailcollectionsrc file. Now KMail sort of worked. Well, I got other errors, but at least it no longer crashed during startup. First thing I wanted to do now is to enable KMail in Kontact again. But when I try to open the Settings -> Configure Kontact menu, Kontact crashes. I tried to report this, but DrKonqui was unable to log in because of timeouts on bugs.kde.org I think. That crash is strange, some days ago the settings menu worked, as I used it to remove KMail from Kontact. Anyway, I edited kontactrc manually, and now KMail shows up in Kontact again. But there are more problems. KMail crashed when saving mails as drafts. I also got warnings about invalid sent-mail, drafts and templates folders. Indeed, those were empty. When setting them back as they were before, I realized that I have more IMAP folders now. For example, one identity had a folder 'Drafts' and 'Entwürfe' (German for 'drafts'), now I also have '.maildir/Drafts' and '.maildir/Entwürfe'. The same goes for 'Sent' and 'Gesendet', now there's also '.maildir/Sent' and '.maildir/Gesendet'. Whatever. Easy to fix, but I do not think KMail should crash because of missing folders. One positive thing to mention: Akregator now asks if it should restore the last session, so I did not lose this when Kontact crashed. Oh, and for a while, whenever I sent a mail, I got a notification: '<account>: Connection to server lost.' This also happens sometimes when browsing mails, I advance to the next unread mail, get the message and an empty message. A more serious problem is that some IMAP account was missing completely. I simply re-created the one I need, the other 1-2 accounts were for testing anyway. On the other hand, I have 'akonadi_localbookmarks_resource_0', showing my Konqueror bookmark folders. Is this normal? Is there any use? I only see the folders and the number of entries, but I do not see the entries itself. Can I delete this somehow, or make KMail not display them? Without removing the bookmarks from Konqueror. And there is 'akonadi_maildir_resource_0', showing my local mails. I probably can remove this completely, as the same stuff appears as 'KMail-Ordner' (KMail folder) already. Yes, seems this did no harm. Then, my main IMAP account did not show all the mails. Some folders are empty. Sometimes. Could this be because I have two IMAP accounts of the same name, one configured to use disconnected mode? I removed this one, and now, after restarting Kontact, it's better. But I lost the mail I am just writing. I saved it as draft before quitting Kontact, and now it is gone. Good thing I put it into the clipboard first, just in case KMail would screw up and lose the mail. It turned out that the drafts folder was empty again. I set it accordingly, and finally all seems to be fine. I had to do some more tuning, like defining my .signatures which were lost, but not much. So, in the end, all seems to be working again. But it would have been easier to start from scratch, define my three IMAP acocunts and identities, and a local maildir.
