Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
Plasma consistently becomes absurdly laggy when I have some remote shares mounted or when I have some files opened over the network via kio.
When there is a lag spike or when I get disconnected from the wireless network under those circumstances, Plasma becomes unresponsive (not just Plasma, but all the applets, and all the KDE applications using those network resources, like Dolphin in the case of file shares, etc.)
If, in this state, I decide to use an application that still works (for example, Kate if it had no files open) and try to access the File Open dialog, then Kate in turn gets hit by the problem (probably because it's trying to communicate over the Internet to see the files in the Open dialog), even if the File Open dialog doesn't display a remote directory.
After a while, I eventually restart X or reboot out of frustration. If I wait, however, Plasma often crashes, and this is one of these crashes.

The crash can be reproduced every time.
