And now you pull the GDK global lock out of the hat to add to the mix!

I would suspect that you are recursively, or out-of-order, locking on
that, given the large number of other locks you seem to have in your
program. It is difficult to use correctly.  

Why incidentally are you using both extra-threaded access to GTK+ with
the GDK global lock and also accessing GTK+ from threads via the idle
handler?  You would normally do one or the other, not both.  Why not
drop the global lock, or drop the idle handlers (preferably the first
of those)?
