Rosegarden segfaults in Leap-15.4

Leap-15.4 Regardless of whether I start qjackctl before or not, launching rosegarden fails with this ~ # rosegarden Cannot lock down 86611866 byte memory area (Cannot allocate memory) Cannot use real-time scheduling (RR/5)(1: Operation not permitted) JackClient::AcquireSelfRealTime error Segmentation fault (core dumped) This kind of error shows up REGULARLY in suse (mostly in Leaps) i.e. it gets fixed and then it's only a matter of time before it start again, been watching the yoyo for years.
