Hm, seems similar to the first trace in bug 499944. How old is your build of master? The fix for that landed a week ago.

IIRC I rebuilt plasma-workspace from master yesterday. I'll rebuild workspace, retest and update this bug.

Rebuild everything to be safe, not just plasma-workspace.

And make sure you're not on an MR branch you checked out for testing; I've been bitten by that before.

After rebuilding `workspace` and re-testing, I didn't see a crash. I'll re-open this if I see it again. Sorry for the noise.
