Bug ID: 400601
Summary: Crash on exit with hanging folder sync
Product: kmail2
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdepim-bugs at kde.org
Reporter: kde at carewolf.com
Target Milestone: ---
Application: kmail (5.9.3)
(Compiled from sources)
Qt Version: 5.12.0
Frameworks Version: 5.52.0
Operating System: Linux 4.15.0-36-generic x86_64
Distribution: Ubuntu 18.04.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
Closing KMail because it was acting strange
- Unusual behavior I noticed:
Something about the outlook365 server had changed so that akonadi couldn't
connect to it. The resulted in two different bugs in KMail.
1) The existing messages were not readable even though I had offline caching
enabled. This could be worked around by moving KMail to offline mode, but it
really should be possible to read messages while a sync is working.
2) Closing KMail causes it to hang for a long while until some kind of timeout
triggers and it crashes.
The crash can be reproduced every time.
-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
