KDE microblogging plasmoid causes screen to go blank

I don’t understand what’s going on. All of a sudden if I try to add the KDE microblogging plasmoid to my desktop plasma-desktop crashes and I’m left with a black screen and a couple task icons in the upper left corner. I can hit Alt-F2 and reun plasma-desktop to bring it back, but WTF? Where can I find the error messages? I’ve looked through all my log files and I don’t see anything wrong. Can’t find anything related to this in Google searches and bot much here either. Anyone else?
