Did you try to umount with the "umount" command from the shell? I can't reproduce it anymore with a fresh svn rev. Closing with WORKSFORME. kdebase rev. 811072 I closed this too early, I can finally reproduce it when unplugging my GSM from USB. (same backtrace) Reopen. Probably related to bug #162634 SVN commit 820380 by aseigo: since Solid may throw stuff at us that we aren't prep'd for, let's just handle it gracefully rather than take down all of plasma, m'kay?

Version: (using 4.00.73 (KDE 4.0.73 >= 20080507, compiled sources) Compiler: gcc OS: Linux KDEBASE rev: 805836 Testcase : - Unmount partitions using gparted (I guess the result would be the same w/ qtparted or even parted) -> Plasma crashes. I could reproduce this crash several times w/ different partitions.
