[apparmor] Kernel-regression?

[Jonas Große Sundrup]

Ok, things get funky, I tried some arbitraty things and found...
interesting behavior:

Namely, I have copied that bashscript /usr/bin/element-desktop to
/usr/local/bin/elementlauncher and copied the profile for
element-desktop to a second file, and only adjusted the path.

So /usr/bin/element-desktop and /usr/local/bin/elementlauncher are
identical, the profile files for the two are identical except the one
opening-line of the profile where they are referring to the two
different paths/executables.

/usr/local/bin/elementlauncher perfectly works and the  apparmor-policy
is applied as specified, /usr/bin/element-desktop.

Moving elementlauncher to either

/usr/local/bin/elementlauncher
/usr/local/bin/element-launcher
/usr/bin/elementlauncher

(and adjusting the path in the profile accordingly) doesn't break
anything, everything works perfectly.

/usr/bin/element-desktop however still yields

/bin/bash: error while loading shared libraries: libreadline.so.8:
cannot open shared object file: Permission denied

Does anyone have an idea what could be going on here?
