Application: kmail (5.7.0) Qt Version: 5.9.3 Frameworks Version: 5.41.0 Operating System: Linux 4.14.10-gentoo x86_64 Distribution: "Gentoo Base System release 2.4.1" -- Information about the crash: - What I was doing when the application crashed and Unusual behavior I noticed: I switched folders and tried to view emails inside those folders. KMail was unresponsive and hung at Retrieving Folder Contents for all emails I tried to view. After a few tries, I closed KMail. When it was already closed, I received the DrKonqi message, that it had crashed. I just tried again to view emails in various folders, clicking randomly on messages. Again the Retrieving Folder Contents "please wait" content was presented to me. This time I waited several minutes, and finally the message contents were displayed to me. Thus I assume that this "hang" or unresponsiveness is not actually a bug, but simply related to high load and slow disks. (I am compiling software, just recently migrated my LVM volumes to a new cache device, hence am hitting slow / uncached blocks at every read operating, loading emails in Akonadi/KMail and apparently Baloo is also active). -- Backtrace: Application: KMail (kmail), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

Since KMail seems to hang more or less indefinitely (as long as Baloo is pressuring the disks), closing KMail seems to ease the reproduction of this crash - even if KMail is "Retrieving Folder Contents" for several dozens of minutes, it will crash shortly after I close it.

The problem appears to have more to do with akonadi, kmail's backend, than kmail itself. If akonadi tries to synchronize a very large remote IMAP folder, it can become unresponsive; when this happens, kmail will wait indefinitely for a response from it. Killing akonadi and restarting it appears to temporarily resolve the issue.
