Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.85 (KDE 4.4.85 (KDE 4.5 Beta2))
Qt Version: 4.7.0
Operating System: Linux 2.6.34-020634-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I tried to move picture widget, it was OK but few seconds later plasma crashed.
- Unusual behavior I noticed:
Xorg have memory leaks (consumes more than 500MB) and it uses about 50% of CPU after e.g. day of using. This problems wasn't there before I updated to KDE4.5beta2.  The OS is very slow because of this. I tried to update newer xorg via xorg-edgers but it has no effect on this. The effects are faster due to the newer NVIDIA driver in this xorg-edgers.

Thanks for help in advance, despite of this problem, KDE4.5 will rocks! :o)
