likely due to a third party plasmoid (or possibly akonaid integration) not loading and throwing an exception. the backtrace, however, does not tell us anything about what is happening as all it says is "an exception was thrown at a bad time", though the mentioned cause is what every of these situations we've investigated has turned out to be. so .. i recommend removing your plasma-desktop*rc files in ~/.kde/share/config and starting again

could be the akonadi bug that was fixed recently (calendar integration had an issue, which the clock uses by default). the backtrace is still unhelpful, however.

I was used to have the same issue, it was really annoing, it was solved after I removed all my calendar from Kontact (Korganizer). I'm telling this because Aaron said there was a bug in calendar integration that is solved; so perhaps installing the latest version of akonadi could solve this issue.
