Cynthiune crashes when attempting to play a WMA file (or adding such
file to the playlist).  This worked perfectly well with previous avifile
releases (at least with the sample files available at
http://samples.mplayerhq.hu/A-codecs/WMA/).

Here's the backtrace:

At first glance it looks like libav10.patch is not entirely correct
and/or complete.

That is still the case but the backtrace is different.

Here's an updated backtrace with the current (1:0.7.48~20090503.ds-29)
version, this time on amd64:
