Application: kontact (5.0.2) Qt Version: 5.4.2 Operating System: Linux 4.2.0-16-generic x86_64 Distribution: Ubuntu 15.10 -- Information about the crash: - What I was doing when the application crashed: I closed Kontact. - Unusual behavior I noticed: read rss messages were not marked as read on opening before I closed kontact. this happens about once a day, or once evry 2 days since the update to kubuntu 15.10. akkregator seems out of sync. messages are not being marked as read. The number of new messages shown in a feed does not correspond to the actual number of unread messages in the feed. when kontact is closed -> crash. often even with a corrupted feed list after a restart. The crash can be reproduced sometimes. -- Backtrace: Application: Kontact (kontact), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/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.
