libpurple should be able to run on a thread, but it is vital that you  
ensure that *all* messages to libpurple are sent on that thread, as  
libpurple is not safe for interthread interactions.  Are you managing  
the glib run loop such that it iterates on your libpurple thread?

Are you sure you really need to run libpurple and glib on a thread in  
any case?  A lot of effort has gone into ensuring that libpurple acts  
in a non-blocking fashion for networking operations and most time- 
consuming calls.
