Description Elias Probst 2011-08-22 12:55:01 UTC
Application: kontact (4.7.0 )
KDE Platform Version: 4.7.00 (4.7.0) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.39-gentoo-r3 x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
- What I was doing when the application crashed:
This bug can be easily reproduced here by doing this:
→ Start Kontact
→ Go to the KMail component
→ Open the Sieve dialog (Settings → Manage Sieve Scripts)
→ Close the Sieve dialog
→ Kontact/KMail crashes

This does also happen when running KMail standalone.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault

Comment 1 Elias Probst 2011-08-22 13:04:54 UTC
It seems this crash does not happen, when editing a script and using "OK" afterwards, which means the Sieve dialog updates the script on the server.

This means the crash does only occur, when no upload to the server happened.
Comment 2 Laurent Montel 2011-08-22 16:50:37 UTC
I can't reproduce this crash.
Comment 3 Laurent Montel 2011-08-22 16:51:49 UTC
Do you have several script ?

(In reply to comment #3)
> Do you have several script ?
One server with 1 script
One server with no scripts
See also attached screenshot.
Comment 5 Laurent Montel 2011-08-22 22:13:54 UTC
Ok for the moment I can't reproduce it
Will continue
Comment 6 Damien Gombault 2011-09-13 13:32:14 UTC
I also have this crash with the same stacktrace on Arch Linux 64 bits and KMail 4.7.1.

I open the Sieve config dialog, close it then I get the crash.
I have one IMAP account with no Sieve script (yet).

Comment 8 Murz 2011-09-29 16:30:18 UTC
As I describe in Bug 283012, it crashes only if can't connect to Sieve server, if connection is successful, it isn't crash. Hope this helps solve issue.

Git commit 53fd6b2eeba7d2aa8144be984fd7b82b5f1f4671 by Montel Laurent.
Committed on 29/09/2011 at 19:14.
Pushed by mlaurent into branch 'master'.

Fix Bug 280568 - Kontact/KMail crashes when closing the Sieve dialog

When we call kill() we send a signal result() and result remove job in mJobs
=> list of mJobs is not good after that.
So when we close dialog we disconnect signal before to call kill and mJobs is clear at the end of function

FIXED-IN: 4.7.2
BUG: 280568
