-- Information about the crash:
This seems to be a duplicate, but I am not sure. What seems to be different from other reports I read is that the crashes happen without me doing special things, like logging out or closing Amarok. I have Amarok running, but it does not seem to be affected. I can leave the PC alone for a while, and when I come back plasma sometimes has crashed. Oh, and it did so again while I was typing the last sentence.

I updated to KDE 4.6.1 three days ago, but the crashes started happening yesterday. Well, plasma crashes frequently here, so it may have happened earlier and I forgot, but not that often as it does now. No idea what could have triggered this behaviour. I did not log out of KDE after the first login after the update, I did not install plasmoids or make other changes to the configuration. An hour ago I logged out and in again to see if this would make a difference, but it did not.

If you like me to do so, I could compile plasma-workspace and whatever else you like with debug information.
