New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.7.2 (4.7.2) "release 5" using Qt 4.7.4

- What I was doing when the application crashed:

Shutting down my laptop. Every damned time I shut down this happens. I walk away thinking "Oh! It'll shut down by itself" and return - sometimes hours later - and go "Oh! It's still running, wasting power, with a window left open on screen". FFS!

> Every damned time I shut down this happens.

Since this bug is marked as fixed in KDE 4.7.4, why don't you update? By the way, we already released KDE 4.9.1, which has many more bug fixes.
