Same problem on Fedora Core 9.   I see there is no update to the parser to set 
this
field correctly yet in the svn repository ?

I'm experiencing the same thing on Ubuntu 8.04
I've had trouble before with subprocess.Popen and programs that want to do fancy
things with the terminal (like ffmpeg).  
I'm now playing with gdb via the newish python pexpect module;it's working well

Same problem on Debian with pygdb-0.2

It looks like GDB is allowed to return no result (see 
http://sourceware.org/gdb/current/onlinedocs/gdb/GDB_002fMI-Result-Records.html)

My quick-fix is to change

 while not self.result:

to

 while self.status == 'pending':
