Bug ID: 357299
Summary: kmail crashes during some curious activity done
simultaneously in all folders above the one I moved a
message into
Product: kontact
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdepim-bugs at kde.org
Reporter: michael.brach at uni-muenster.de
Application: kontact (4.14.3)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 3.13.0-74-generic x86_64
Distribution: Ubuntu 14.04.3 LTS
-- Information about the crash:
- What I was doing when the application crashed:
1. On the left I have my folders view, say there are 20 folders. In the middle
I have my message list, on the right a certain message text is shown.
2. Using the mouse, I grab this message from the list and move it into the one
folder, say it is the 9th counted from the top.
3. When I would release the mouse button above the 9th folder, something would
happen in all folders from the 1st to the 9th, indicated by an icon with a a
rotating arrow, which is shown instead of the normal folder icon.
After 5-15 seconds,
a) the activity is over, I can work normally
b) kmail would crash
I cannot say when point 3 will happen, It seems to be in the beginning of daily
work. However, it is not each time (each day and it may happen more than one
time per day. For instance, if (3) happens, and case (a) happens, I would move
another message into folder 12, then the same (3) would happen again. I think
that it would not, when I move a message to say folder 4 (a folder above
folder 9). But I'm not sure at the moment.
I tried to differentiate the issue and move messages by using the context menu.
I never experienced the problem this way. Maybe it is a problem with the mouse?
HOwever, only in kmail I have unexpected behaviour.
MAybe s.o. can give me a int where to watch, or what to triy out.
The crash can be reproduced sometimes.
