symbol problem in aegisub and ffms

Hi,

it seems that libffms from sid cannot link with DMO's libavformat,
making aegisub unusable:

$ aegisub
aegisub: relocation error: /usr/lib/libffms2.so.2: symbol
ff_codec_bmp_tags, version LIBAVFORMAT_53 not defined in file
libavformat.so.53 with link time reference
