Summary: Assertion in Audio::Timestamp::addInternal() with MI1 CD

Initial Comment:
Hi, 

I just recompiled ScummVM with today's SVN and now I'm hitting this assertion every time (reproducably) in Monkey 1 VGA CD (english):

these are the variables in question:

ts = {_secs=-96 _numFrames=1080 _framerate=3000 ...}
_framerate = 441000

apparently, something is wrong with the frame rate.

This is on Win32 with MSVC 2008 (everything self-compiled), and I'm using FLA audio since MP3 doesn't seem to work for me anymore.

If I click on "continue" everything works and the game plays normal from that point on (at least as far as I've played... about 5 minutes in)

I've uploaded a coredump here if that is of any help: cornelia.regengedanken.de/~mdrueing/temp/scummvm_debug_dump.zip
