Hi.
Below are the BTs and strace...
At a first glance it seems that this is somehow related to sound
output,... it seems to always hang when sound was or is about to be played.
IRC is just "special" here, as I get the initial hello message from
NickServ, which makes sound.
Deactivating sound in pidgin stopped it from hanging (till now)
Cheers,
Chris.
