can you ensure that kdebase/apps/plasma was also built and installed recently? this looks like a possible binary compatibility issue, so it would be good to rule that out first.
I'm always updating kdelibs, kdebase and kdeplasmoids at the same time to avoid this kind of problems.
It didn't happen in recent SVN. I think I updated at a wrong moment when it hapenned. So, I'm marking this bug as resolved.
*** Bug 164934 has been marked as a duplicate of this bug. ***
Reopening, I think it requires some more investigation.
Bram: if this really is a duplicate of this bug, then it's a problem with the reporter's install. looking at the two backtraces, i'm not even sure they are the same issue. the BT on 164934 doesn't contain any useful symbols in any case. it probably is another "my plasmoids fell out of sync with libplasma". there were a couple of BIC commits in the last few days.
It doesn't seems to happen anymore, so I think Aaron is right. I should have updated at a bad moment when this bug happened.
