Bug 314856

Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.7.0-7-generic x86_64
Distribution: Ubuntu 12.10

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

Set-up:
KDE 4.9.4
Google Chrome (24.0.1312.56-0ubuntu0.12.10.3) opened, many(20+) pinned tabs in it with a youtube music video running.(Flash Player 11.2.202.262)
something like 2-3 Dolphin (2.1) windows opened.
Sublime Text 2.0.1 Build 2217

-->While in Kconsole (2.9.4) with 3 tabs opened (1 with Make(cMake test stage) running, 2 others idle) , while in an idle terminal, i used my custom configured shortcut for minimising ALL windows : SUPER-D (like Win7 shortcut)
...and crash.

Note that aside of plasma and some cMake errors, all programs kept running like nothing happened.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Outil de gestion de fenêtres Plasma (plasma-desktop), signal: Segmentation fault
