Unsure if this is related, but symptoms are the same: sudden crash while doing nothing of mention: in this particular case, hitting back in firefox. This may have caused the raising of an auto-hide panel in the left side of the screen, but could be unrelated. No way to reproduce. After each crash, my dashboard widgets revert to some early configuration. Very frustrating.

What the situation on KDE 4.2.2 or trunk? Is Plasma still randomly crashing ?
We received a duplicate report of the crash reported against KDE 4.2.2. (https://launchpad.net/bugs/366370)
I've changed my setup to use qt-copy from trunk. With qt 4.5.1 this crash doesn't happen so far.
@Michael: that's promising. let's see if it goes well during the upcoming betas for 4.3. if you don't get this crash between now and then, then we can close this one.
