I encountered this crash in Tomboy, immediately after checking the preference Hilight Wikiwords. I was able to set it subsequently so it's either intermittent or just random that I had done that prior to the crash.
This traceback may help isolate it, as I happened to have run it from a shell. Sorry, I don't have the -dbg package installed.
