svn crashes when excluding icon from filters bar

[Ken Moffat <kmoffat drizzle com>]

I am running the latest svn on debian testing, and f-spot crashes with 
the below error when I either right click/exclude or double click an 
icon on the filter bar. Probably a debian testing incompatibility, but 
thought I'd mention it.
