This looks like a bug in the slider/painter code.
Maybe some ranges are screwed, like 0 to 0 or so and the slider
can't handle it.
A gdb backtrace would be helpful.
Could you compile with:


and then create a backtrace with gdb:

echo -e "run\nwhere\nquit" > gdb_com.txt
gdb src/alsamixer-qt4 -batch -x gdb_com.txt > gdb.txt

and send me the gdb.txt file?

Right now I only have a mercurial repository on my local machine.
I think sourceforge support mercurial now, I'll check on this later.

I would like to avoid keeping a blacklist in the mixer application.
It's meant to be a general purpose mixer but it should'n crash on high
end hardware.
