It'd help to have a full backtrace to be sure, but I found this upstream
bug that seems likely to match:

  https://bugzilla.samba.org/show_bug.cgi?id=15599

That bug has patches for 4.19 and 4.20.  Essentially, the fix checks for
an uninitialized GPO security_descriptor and bails out of marshalling to
avoid the crash.

I've verified that our 2:4.20.4+dfsg-1ubuntu1 in oracular and plucky
already carry this fix, but noble does not.  The functionality appears
to be missing from jammy, and given that upstream fixed only 4.19 and
4.20, am gathering the fix is not relevant there.
