Application: plasma-desktop (4.11.3)
KDE Platform Version: 4.12.0
Qt Version: 4.8.2
Operating System: Linux 3.2.0-58-generic-pae i686
Distribution: Ubuntu 12.04.4 LTS

-- Information about the crash:
- What I was doing when the application crashed: I was typing in google spreadsheet when my softphone (jitsi) rang.  I switched virtual desktops to answer it.  Then, while still on the phone I opened NixNote which was running in the tray.  Within a few seconds, plasma crashed.

This is not the first time this, or other programs have crashed.  What may (but shouldn't) be part of the issue:  I installed the system using debootstrap and the mini iso.  I then installed kde-desktop and built up from there.

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