Application: plasma-desktop (4.11.10)
KDE Platform Version: 4.12.5
Qt Version: 4.8.6
Operating System: Linux 3.15.4-200.fc20.x86_64 x86_64
Distribution: "Fedora release 20 (Heisenbug)"

-- Information about the crash:
- What I was doing when the application crashed:
I had just changed the display layout (between laptop and external monitor, moved from left to right) and the panel was half the length. I tried to adjust it but it did not work (size controls kept disappearing), then I removed it and tried to add it again (Default Panel). I got the crash.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
