In general, assertion() means a bug in the code. Please file an issue
against gst-plugins-bad repository on
gitlab.freedesktop.org/gstreamer/gst-plugins-bad. We'll have to sort
out if this bug is in pitch or audioconvert, but -bad is good place for
now.

p.s. Please report the versions, a bonus would be to check if it was
also broken in older version of GStreamer. If not, then just mention
it's a regression and we will treat it as such.
