Well, from that description, it sounds to me like your UI thread (which
is probably your only thread) entering an infinite (or simply very long)
loop or is blocked on something that never happens.

Tools that I use to diagnose this sort of problem include strace, gdb,
and printf-debugging. (Recall that strace and gdb can be attached to a
running process.) 

(Also, let us know if you need more assistance.)
