Some background first: Applications do not compete or have control over
the GPS at all. Location service is handling all of the access. With
that, an app is not able to block or exclusively own the GPS. There are
multiple other reasons why the apps could appear to not receive any
updates, though. That being said: We have problems reproducing the bug
on latest rc-proposed images. If someone is able to reproduce, it would
be really helpful if we could get gdb backtraces of both apps and the
location service. Please see:

  http://dirac.org/linux/gdb/06-Debugging_A_Running_Process.php

for a good overview of how to attach to a running process. Once
attached, you should enter "t a a bt full" in gdb, and pastebin the
trace(s). Please note that you need to execute gdb with elevated
privileges (sudo) to be able to attach.
