Pull hangs in subsequent runs using libostree

[Jeff Ortel <jortel redhat com>]

I'm running into an issue with libostree in python using gobject.  The 
code[1] performs the following steps:

1. ostree init
2. add remote
3. pull
4. pull  <--- reproduces the issue

The pull in step #4 should return quickly as there is virtually nothing 
to do.  But instead, it hangs indefinitely.  I attached with gdb and 
dumped the stack trace[2].  It appears to be blocked trying to acquire a 
lock.  Another bit of information - step #4 does not hang if step #3 
does not need to pull anything.

Suggestions?

Thanks,

Jeff
