Application: plasma-desktop (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-15-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:

all programs were closed except for one instance of konsole using tmux shell and sudo as "sudo -i" to run updates and upgrades with "apt-get" -- i did upgrade my distribution, including the latest ubuntu kernel. afterwards i ran a few safe, non-aggressive commands to clean and remove outdated files that became as such during &/or after the distribution upgrade.

- Unusual behavior I noticed:

while <meta>+<f2> did call the little modal window into which commands are given, the window was unresponsive -- it flickered a few times while trying to run plasma animations (the window is placed at screen top, middle, & slides in over about 500-1.5k ms -- at this point the plasma desktop crashed, was able to relaunch itself, and prompt me with the option to submit a report.

- Custom settings of the application:

many desktop effects are enabled including window animations.  at least 10 applications have custom window appearance settings, many of which include the dropping of title bar and border in favor of a glowing bevel (and i rely on the mouse or <meta>+<f3> call to the window menu in order to resize or reposition a window set to instance itself without a border or titlebar).

The crash can be reproduced sometimes.
