Description Joe Wright 2014-07-25 21:44:07 UTC
Created attachment 921063 [details]
ccpp file contents from local reproducer

Description of problem:
kwrite segfaults when triple clicking on empty file

Version-Release number of selected component (if applicable):
- kdebase-4.3.4-6.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Open kwrite
2. click 3 times rapidly (as if attempting to highlight a line)
3. crash

Actual results:
- crash

Expected results:
- nothing should happen

Additional info:
I was unable to get the debug packages for the latest version of KDE to run a backtrace. ccpp file contents attached

Does not crash as long as there is something to highlight, including alphanumeric characters and/or empty spaces/lines

Does not appear to be an issue in fedora upstream. Tested on FC19, kde 4.11.5 with no issues

i set the state to NEEDINFOS, it's bette to track the issue, because feedback from testing of the fix is needed.
thanks

Comment 8 Joe Wright 2014-10-23 21:57:34 UTC
Another customer reported the issue. I provided the packages to them.

I tested the package on a virtual machine of mine running RHEL 6.6 and can confirm that the package fixes the 3x click bug in kwrite for me.
