Description of problem:
Muine crashes as soon as it's started.

Version-Release number of selected component (if applicable):
muine-0.8.5-1.fc6
mono-core-1.1.16-1.1
dbus-sharp-0.63-4.fc6
dbus-0.90-8

How reproducible:
Always.

When I start muine, it prints
4362: assertion failed "allocator->lock == mutex" file "dbus-dataslot.c" line 82
function _dbus_data_slot_allocator_alloc
and a stack trace (which I'll attach to the bug), and crashes. No gui is displayed.

I've reproduced this on two computers running fc6test2 and also with a newly
created, "clean" user account.
