Hi, I'm using this version of kde for a while now, and experience in a lot of apps more or less severe slowness (e.g. dolhin, kmail, system settings). In .xsession-errors the following error appears many times: mmap failed for "/var/tmp/kdecache-martin/kpc/kde-icon-cache.index" A few weeks ago a similar issue was discussed in [1], causing slowness. It looks like it's somehow related to qt-4.6. The only bug report I could find is [2], but that related to a crash. I don't have any crashes. Does anyone else see slowness when using qt-4.6?
