It really does sound like the backend's getting stuffed up somewhere.  I'm not 
able to reproduce this, though..  So, here's what I'd like you to do:

- verify real quick that you're running the same CVS checkout on both 
- recompile things on the box running the backend for debugging (edit 
settings.pro), and run the backend inside of gdb (ie., gdb mythbackend, then 
type run at the prompt).
- get it to hang
- in gdb, hit ctl-c to break execution.  
- type 'info threads' at the prompt -- you should see a list, similar to:

(gdb) info threads
* 5 Thread 49156 (LWP 15130)  0x409bdf11 in nanosleep () from /lib/libc.so.6
  4 Thread 32771 (LWP 15129)  0x409bdf11 in nanosleep () from /lib/libc.so.6
  3 Thread 16386 (LWP 15127)  0x409bdf11 in nanosleep () from /lib/libc.so.6
  2 Thread 32769 (LWP 15126)  0x409e02c0 in poll () from /lib/libc.so.6
  1 Thread 16384 (LWP 15121)  0x409e1b1e in select () from /lib/libc.so.6

- What you're going to do is get a backtrace from each running thread, so, for 
each thread, do something like:
   - thread 5
   - bt full
The left column is the thread number..  just do that for each thread, and send 
me the output.. Hopefully, that'll show enough to say where it's getting held 
up at.
