Bug ID: 324776
Summary: kmail crashing repeatedly while idle (or fetching
mail)
Classification: Unclassified
Product: kmail2
Version: 4.10.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdepim-bugs@kde.org
Reporter: ubu...@konfido.net
Application: kmail (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-29-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
Nothing, i.e. kmail was in background, maybe fetching mail via IMAP. It does so
every 5 minutes. This problem occurs (almost?) every time kmail is running for
more than a few minutes.
- Custom settings of the application:
Only IMAP folders, no POP3
The crash can be reproduced sometimes.
-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library /lib/x86_64-linux-gnu/libthread_db.so.1.
