MP3 muxer does not check codec used

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I run what I believe is a conversion from FLAC files to MP3 (see log below), 
but ffmbc crashes with a floating point exception.

What is the expected output? What do you see instead?
I expected to get an MP3 output file, instead the conversion crashes.

What version of the product are you using? On what operating system?
FFmbc version 0.7-rc8
Ubuntu 10.04 LTS

Please provide any additional information below:

- Full commandline run (with -v 3) and everything the program printed
without
the repeating parts.

Of course, I probably shouldn't try to encode PCM in an MP3 stream, but then I 
think I should get a warning about an unsupported codec, rather than a crash.
