after upgrade from Leap 15.0 KMyMoney crashes in XFCE, but works in KDE

After upgrade from Leap 15 (where KMyMoney works OK in XFCE) to Leap 15.1, the application KMyMoney crashes, and does not load. After many re-loadings of both KMyMoney and reinstalls of LEAP 15.1 XFCE to computer including a fresh install not an upgrade KMyMoney still crashes.
When KDE desktop environment added to fresh install, so choice of XFCE or KDE being possible; then:
a) KDE opens KMyMoney OK.
b) XFCE still crashes.
Bug reported to KDE team, but it may be a XFCE package problem.

When starting in terminal under: gbd output of gdb bt gives

Has anyone else this bug?
How to sort?
How to report to XFCE?

regards and thanks in advance.

I’d recommend reporting through the openSUSE bugzilla (https://bugzilla.opensuse.org.
With 15.1, I see significant changes to the core/base components pattern, my guess is that the previous pattern provided some components that aren’t in the new pattern, and the application package wasn’t built against the new pattern (simply updated from previous package).

Be sure to create a proper debug log and include with your report.

How to do “Be sure to create a proper debug log and include with your report.”. I have no experience of this, but can follow (I hope) instructions. Please advise how to do or provide link to instructions.

[Meanwhile added KDE to system and it operates KMyMoney no problem. However I prefer XFCE.]
Thanks in advance
