Bug#711107: gtk+3.0: FTBFS on ia64 and mips

Hi Stephan,

Thanks for your analysis! I indeed get a conditional jump based on an
uninitialized variable on x86_64. I have forwarded your bug report upstream at

https://bugzilla.gnome.org/show_bug.cgi?id=702370

As for the mips failure, I ran it on valgrind on x86_64 in case it was a similar
issue and oh surprise, it fails under valgrind, even though there are no errors
(well there are two but are suppressed, I haven't checked why but I'm assuming
if they are suppressed then they are false positives).

I have reported it with some more information at:

https://bugzilla.gnome.org/show_bug.cgi?id=702371

I'm making an upload with your patch and with the failing treeview testcase
disabled for now.

Thanks again!

Cheers,
Emilio
