Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.1 (4.8.1) "release 483"
Qt Version: 4.8.0
Operating System: Linux 3.1.9-1.4-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

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

Nothing. I clicked on a folder. It crashed.

- Unusual behavior I noticed:

None that I observed, prior to the crash, *except* if I log out the layout of just that one widget (Folder View) is not saved. it (frequently, but not always) changes geometry from where I had it to where it is at startup.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
