Git master from Jan 4th builds fine, so something broke between then and now.

For gstreamer 1.7.1:
% git branch -v
* master 438a83d controller: Do not unset uninitiallized GValue

19:34 < kwm> is this known or should I file a small bug report?
             http://dpaste.com/1PKN96V
19:49 < __tim> I haven't seen it before
19:49 < __tim> this is in an installed or uninstalled setup?
19:50 < __tim> there's a problem with the uninstalled setup on some systems
               because of some libtool path order thing, maybe you're running
               into that too
19:51 < __tim> but even more, it shouldn't be loading plugins in docs/gst/
               anyway, I think
19:56 < kwm> __tim: uninstalled
19:57 < kwm> 1.6.2 is installed
19:58 < kwm> __tim: I haven't updated gst-plugins-base (which is from jan 4).
             The gstreamer checkout from master of the same date had no problem
             building.
19:58 < __tim> yeah, it must be pulling in the installed old
               libgstreamer-1.0.so, but I'm not sure why
19:59 < __tim> docs/gst/Makefile.am has the .la files to the core libs there,
               so it should be using the local ones
19:59 < __tim> unless the problem is the order, can you check if moving
               $(GST_OBJ_LIBS) to the end in GTKDOC_LIBS =  fixes anything?
20:01 < kwm> __tim: no luck
20:02 < __tim> dunno then, I blame libtool :)
20:09 < kwm> __tim: right :), will file a bug later with the above info, I
             guess then
20:11 < __tim> I think you'll have to dig through the libtool scripts to see
               what's going on ;)
