Permission to break hard code freeze - Fix tracker_sparql_connection_query_async() crash

[Martyn Russell <martyn lanedo com>]

Hi all,

Debarshi Ray has submitted a patch in the last 24hrs which fixes a crash 
in a VERY COMMON API in Tracker. The 
tracker_sparql_connection_query_async() API can crash if the 
GCancellable is cancelled on one of two async APIs called in parallel 
leaving the second async operation waiting indefinitely or crashing.

The details are here:
https://bugzilla.gnome.org/show_bug.cgi?id=737023

I've checked the patch myself and also Jürg has confirm the patch looks 
good to him too.

Releases are planned this afternoon if all goes well,
Thanks all,
