Hm, this is a horrible combination for debugging: a binary-only app
plugin from another app....  The backtrace shows the function: that's
good.  But, it shows the very first line of the function.  So, it
can't tell where actually hits.  It makes hard to guess...

And, I can't reproduce the bug.

The reporter can try the following, at least:
 - uninstall alsa-plugins package to see whether it's a speexrate
   plugin issue
 - update packages from OBS multimedia:audio:libs repo, to be sure,
   whether the problem got fixed in the later versions
