Bug ID: 401923
Summary: KMail crashes randomly in connection with the display
of Emails (probably a problem with Nouveau)
Product: kmail2
Version: unspecified
Platform: Chakra
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdepim-bugs@kde.org
Reporter: i...@cyrilbrosch.net
Target Milestone: ---
Application: kmail (5.9.3)
Qt Version: 5.11.2
Frameworks Version: 5.52.0
Operating System: Linux 4.18.12-1-CHAKRA x86_64
Distribution: "Chakra"
-- Information about the crash:
- What I was doing when the application crashed:
Very often during use, when I click a new mail in order to do any action (view,
delete, copy, etc.), but sometimes also during startup or closing the program,
KMail crashes. It's hard to work longer than 5 mins with it without a crash.
I finally got a usable backtrace after the update to Plasma 5.14.4, frameworks
5.52.0, Qt 5.11.2, but this happened also in the versions before that, but not
before the latter versions, so the bug was introduced somewhen this
spring/summer, I guess.
I can't read backtraces, but I see Qt and Nouveau driver pop up there many
times.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KMail (kmail), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
