Bug ID: 321625
Summary: KMail crash when switching off tray icon
Classification: Unclassified
Product: kmail2
Version: 4.10.3
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: kdepim-bugs at kde.org
Reporter: andreash87 at gmx.ch
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".
