[Evolution] Evolution 2.6 crashes on startup

["Jamie Penman-Smithson" <jpenman smithson gmail com>]

Recently evolution (2.6, gnome 2.14) started crashing on startup right
after loading the CalDAV eplugin.

(gdb) run

I've tried moving the ~/.evolution directory out of the way, in case
it was an issue with my configuration, no luck..

This is probably peculiar to this system but I'm unsure how to further
diagnose the issue. Any hints would be appreciated.

Thanks in advance,
