Application: kmail (4.10.3) KDE Platform Version: 4.10.3 "release 1" Qt Version: 4.8.4 Operating System: Linux 3.7.10-1.16-desktop x86_64 Distribution: "openSUSE 12.3 (x86_64)" -- Information about the crash: - What I was doing when the application crashed: I had trouble with KMail stalling while trying to load mails from an IMAP folder. I tried fixing this by killing KMail, Kontact, and KWallet. That didn't do the trick though. What finally helped was to switch to offline mode and back to online mode. Mails were loading again. However, the notification Icon in the systray didn't survive all the killing. I tried "turning it off and on again". I.e. I went to the settings and switched the sys tray icon off. In that moment KMail crashed. -- Backtrace: Application: KMail (kmail), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

Created attachment 85878 [details] New crash information added by DrKonqi kmail (4.13 beta3) on KDE Platform 4.12.95 using Qt 4.8.6 - What I was doing when the application crashed: I minimized KMail to the system tray when it segfaulted. -- Backtrace (Reduced): #6 0x00007fc81020cab3 in KMKernel::toggleSystemTray() () from /usr/lib/libkmailprivate.so.4 #7 0x00007fc81023cdcf in KMMainWidget::readConfig() () from /usr/lib/libkmailprivate.so.4 #8 0x00007fc81023cef9 in KMMainWidget::slotConfigChanged() () from /usr/lib/libkmailprivate.so.4 [...] #14 0x00007fc810e146f3 in KDialog::applyClicked (this=this@entry=0x1a64d70) at ./kdialog.moc:259 #15 0x00007fc810e14d46 in KDialog::slotButtonClicked (this=0x1a64d70, button=8) at ../../kdeui/dialogs/kdialog.cpp:888
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
