Application: kmail (4.14.9) KDE Platform Version: 4.14.9 Qt Version: 4.8.6 Operating System: Linux 4.1.0-4.gbab8328-desktop x86_64 Distribution: "openSUSE 13.2 (Harlequin) (x86_64)" -- Information about the crash: kmail left running in background. After some time it crashes. I do not see any specific pattern to the crashes; they happen from time to time, and I am not able to conciously reproduce them, as I do not know what I do to produce them. If anyone has suggestions for what to attempt, please sound the horn to me :) The crash can be reproduced sometimes. -- Backtrace: Application: KMail (kmail), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

This bug has never been confirmed for a KDE PIM version that is based on KDE Frameworks (5.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 oportunity 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 more recent), please open a new one unless it already exists. Thank you for all your input.
