You are using an intentionally broken version of FFmpeg that 
contains several hundred regressions over FFmpeg (bugs that 
are not present in FFmpeg, but are present in the 
intentionally broken version that is installed on your system).
Some of those bugs look security relevant, so please understand 
that we cannot support this version.
(Apart from that, it does not support alpha in bmp.)
Please look at http://ffmpeg.org/download.html for a list of 
supported versions (that does support alpha in bmp), I am quite 
sure that pre-compiled binaries for your distribution exist.

Unrelated: I consider it slightly inappropriate if you are 
asked to post complete, uncut console output and you post 
heavily cut console output, please remember that everybody 
is posting here voluntarily, so not following the rules of 
this mailing list and not answering the questions asked is 
probably not a good idea if you want support.
