Is OpenGl acceleration working? Are compiz or beryl running? They had problems 
with multiple OpenGl port views. Any console output?

Any way, SMSTools has known X access race conditions, it may not work with a 
concrete video driver.

It is something the application should cope (audio device busy) in a different 
way than crashing. Way for the eventual SMSTools rewrite or better, send a 
patch ;-)

Could be. Check the console output. A dot means that there is some underruns 
so you could need some realtime privileges.

The proper way of adding it is using the 'with_fftw3' scons configure flag in 
CLAM. Anyway this need was a temporary need. I added some code in clam that 
used fftw3 without the mandatory #if USE_FFTW3. Sorry for that. Now it should 
be fixed. Also Pau said in a previous mail that he changed the defaults so if 
you want to use fftw2 instead fftw3 as it was now you should indicate that on 
the 'scons configure' explicitly.

Is feisty the stable one now? Ups, so let's move on to the next one. 
Gutsy? ;-)
