[GnomeMeeting-list] Gnomeeeting 1.2.0 hangs on start-up

[Steve <steveoldmanse-gnomemeeting yahoo co uk>]

Hello

When I run Gnomemeeting 1.2.0, it hangs with the
splash screen window displayed but empty. If I run
from a console, I get the following message twice:

** (gnomemeeting:26849): CRITICAL **: file
orbit-adaptor.c: line 19
(ORBit_ObjectAdaptor_set_thread_hintv): assertion
`thread_hint >= ORBIT_THREAD_HINT_NONE &&thread_hint
<= ORBIT_THREAD_HINT_ALL_AT_IDLE' failed

I have no idea where to start with this one! So again,
any clues?

Thanks
