Rosegarden segfaults

Much too often an update ends up ruining my
music apps group on SUSE. This group includes
qjackctl, qsynth, rosegarden, jack_capture,
Audacity, sometimes Hydrogen as well. It's
gettin' to the point that I'm scared to start
any update.

This time it's Rosegarden... on Leap-15.2
because that's what I'm using right now
(it don't work on Tumbleweed either). Neither
does jack capture on either of them.

Leap is updated, reference Rosegarden-20.06,
all dependencies satisfied

If I launch jack_capture in a cLi window it launches but the dB bars are dead and it records flashes but no music to speak of.
