Description Charles Faulkner 2017-07-29 18:15:46 UTC

Application: plasmashell (5.5.5)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.8.0-36-generic i686
Distribution: Ubuntu 16.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:  I was installing Audacity via a Konsole window, using apt-get install (and running in the window as root using su).  The procedure for obtaining all the required files had been completed, and final installation was taking place, when the konsole window froze. 

- Unusual behavior I noticed: Artefacts on the display when I was closing other desktop windows behind the konsole, also the machine became very slow and lagged to keyboard and mouse input.

- Custom settings of the application: The konsole was running a customized profile, using Black on Light yellow with large text (size 22 font due to visual issues).

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
