Comment 3 Benjamin M 2011-10-14 09:56:49 UTC

I have had a very similar problem. I was seeing how small I could get a horizontal top panel, it made Plasma crash. This is 4.7.2 with openSUSE packages.

Here is my backtrace:

New crash information added by DrKonqi

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

- What I was doing when the application crashed:
The same problem as for original poster. Setting panel size to minimal causes plasma crash.
