Hi! If I do the following within Thunderbird 3.1.9: *) create a folder "test" *) create a subfolder within "test" called "test2" *) copy a message to test *) copy a message to test2 *) rename "test" to "testx" the result in thunderbird is: *) a folder "testx" with subfolder "test2" *) both are *empty* a reconstruct is needed to make them visible again: $ reconstruct -r user.xxxx.testx user.xxxx.testx uid 1 found - adding user.xxxx.testx user.xxxx.testx.test2 uid 1 found - adding user.xxxx.testx.test2 Renaming a folder again before reconstructing it wipes the message files from disc. I filed a bug: http://bugzilla.cyrusimap.org/show_bug.cgi?id=3434 Regards, Wolfgang -- Wolfgang Breyha <wbreyha@xxxxxxx> | http://www.blafasel.at/ Vienna University Computer Center | Austria ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
