Not really a "good" reason, other than that I was using gstreamer 0.10 to build frogr because I only need it for a very small thing (video thumbnails) and I knew that worked in previous releases (and I'm kind of constrained in terms of time to experiment).

That said, I can of course try building with gstreamer1, although I would still need the patch if I want to go with the gstreamer modulesets in 'modulesets-stable' or 'modulesets' (which I'd rather go with), since the version/revision in those ones are 1.0.2 and the 1.0 branch, which do not include this fix (included in the 1.2.1 release, as you pointed out).

So, perhaps it would still make sense to include this patch for both gstreamer 0.10 and gstreamer 1.0.x in the stable modulesets. What do you think?
