Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: firefox has an extremately slow performance

- Unusual behavior I noticed: En el plasma ninguno, sólo observé que el sistema, en general, se veía ralentizado (el cursor se retardaba en desplazamiento y activación de clicks por ejemplo)

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