Application: kontact (4.14.9) KDE Platform Version: 4.14.9 Qt Version: 4.8.6 Operating System: Linux 3.16.7-24-desktop x86_64 Distribution: "openSUSE 13.2 (Harlequin) (x86_64)" -- Information about the crash: I am experiencing extremely slow retrieval of IMAP email. While waiting and searching for solutions Kmail generated this crash. Following one suggest work around I did check "Download email for off-line use" Other than that one change nothing else was changed. Crash occurred prior that change as well. The crash can be reproduced every time. -- Backtrace: Application: Kontact (kontact), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

This bug has never been confirmed for a Kontact version that is based on KDE Frameworks, except possibly a Technology Preview version 5.0.x. Those versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the opportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it. Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.1 aka 15.12; preferably much more recent), please open a new one unless it already exists. Thank you for all your input.
