Bug 286830

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

I have three HTTP picture frames open, for each one there is a different http image that must be reloaded every 10min (are webcams snapshots).

1 - I cannot keep three different images opened, when I reload the third, the first change and became the same.
2 - It crash often: really often, just a reloading or a resizing can crash it.

Thanks

The crash can be reproduced some of the time.

-- Backtrace:
