ecording audio with sweep works quite well, but when i try to record a
second audio stream and sample it over the first one, i need to adjust
the ratio from previous to recorded sound gain in the "record" box.
this causes a segmentation fault on my amd64 debian/unstable system.
i use a new file created at the start of sweep, and it doesn't matter
whether i save this file before adjusting the gain ratio.
the bug is obviously amd64 specific, as sweep in my i386 chroot doesn't
segfault.
