Bug#512466: libavcodec52: Undefined symbol av_lfg_init

[Marcus Lundblad]

Package: libavcodec52
Version: 3:0.svn20090110-1
Severity: normal

I installed gstreamer0.10-ffmpeg and libavcodec52 from experimental since I
needed those for development (yes I know it can be risky doing so on a 
system running testing), however now there seems to be a linkage to a missing
symbol.

If I run:
 gst-inspect-0.10 speex
(actually the name of the element isn't important for this to happen)

I get:

(gst-inspect-0.10:7389): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstffmpeg.so': /usr/lib/libavcodec.so.52: undefined symbol: av_lfg_init

If I do:
objdump -T /usr/lib/libavcodec.so.52 | grep lfg_init

I get:
0000000000000000      DF *UND*	00000000000000a6              av_lfg_init

I'm not sure if this is gstreamer-0.10-ffmpeg linking to undefined stuff or
the library libavcodec52 that fails to export symbols properly.

Also, I think this looks suspicious:

Should it link to both libavcodec52 and libavcodec51?

Thanks!
