xvmc log obtained via RADEON_DEBUG=all

Having a similar problem on a R420.
When using mplayer -vo xvmc to play an MPEG-2 file (recorded from DVB) I can only see a window filled with a majority of green squares flashing.
On stderr, the following message is shown:

r300 FP: Compiler Error:
compiler/r300_fragprog_emit.c::begin_tex(): Too many texture indirections
Using a dummy shader instead.

I then played the same video setting the RADEON_DEBUG environment variable to "all", because I don't know what can be excluded. I then cut the lines following
the error message from the log, assuming those where the lines regarding the dummy shader used as a failsafe by the r300 driver.
I'm using a self-compiled git snapshot of mesa obtained on 2012-02-15 on a Slackware64 13.37 running kernel 3.2.6.
Please tell me if more info are needed.
