[Comment from a bug report cleaner]
From bug 283182 (KDE SC 4.6.5):
- What I was doing when the application crashed:
seeing a mkv film in full-screen mode,
search konsole in desktop inputbox,
launch konsole.

- Updated backtrace:

Are we sure this one is fixed? Just added a duplicate with 4.8.0
Comment 9 Thijs 2012-06-22 08:06:36 UTC 
bug 302315 looks to be another duplicate of this one, but was reported with 4.9beta.

Hello!

This bug report was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this bug is already resolved in Plasma 5.

Accordingly, we hope you understand why we must close this bug report. If the issue described  here is still present in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting

If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging

Thanks for your understanding!

Nate Graham
