[GEM-dev] Gem doesn't render with Mesa 6.5.2

Hallo,
in trying to see if the Mesa-bug that lets Pd crash when the Gem
window is closed has vanished I installed the bleeding edge
Debian-experimental packages for mesa/dri 6.5.2-3.
Unfortunately the crash still happens:
#0 0xb55447f0 in ?? ()
#1 0xb798b904 in glXMakeCurrentReadSGI () from /usr/lib/libGL.so.1
#2 0xb798bbc3 in glXMakeCurrent () from /usr/lib/libGL.so.1
#3 0xb7b133a7 in GemMan::destroyWindow () from ./Gem.pd_linux
however that's old news and already reported [1].
What's new is this: Gem (current CVS) doesn't render anything anymore!
The Gemwin just stays empty if rendering is turned on. (glxgears still
works.) Does anyone have any idea how to debug this phenomenon?
I hope, that Gem and Mesa aren't slowly becoming a couple that's been
married for too long and about to divorce now. ;) As Mesa is without
alternative on Linux, this would be really bad. (At least PyOpenGL
still works fine.)
Anyway here's my current glxinfo:
