Comment # 6 on bug 1205918 from Stefan Hundhammer

We just discussed this in IRC, and it turned out that the test was improved as
well, so the problem was there for a long time (since SLE-15 SP4 / Leap 15.4),
but undiscovered.

So the fix should be released for SLE-15 SP4 / Leap 15.4 as well since it's a
crash, and it's security relevant since changes to those LSM settings won't be
saved, and there won't be an error about it. No installer self-update is
needed, though, since this runs from the YaST control center in the installed
system, not during installation.
