[kde] [Bug 502449] After creating a vault on desktop and moving it the session crashes

--- Comment #2 from krblanc at protonmail.com ---
So, I tried to crash the user again, an use coredumpctl to create a backtrace,
as requested. When I managed to make coredump work, It only listed a few lines
about kdewallet, but nothing about vault or anything else, I am not sure if the
wallet actually had information.

BUT, I managed to fix the crash. Kind of. I couldn't use the coredumpctl at
first because I didn't have enough permissions. This actually reminded me that
the user is a Selinux confined user with user_r role. If I temporarily put
selinux enforce on 0, coredumpctl worked. Also, when I tried to crash again the
session with what I described above, it didn't crash anymore. So the problem
was actually Selinux.

I am sorry to post a crash that was actually a Selinux. I know (i think i read
somewhere) that fedora does not recommend using confined users yet since the
default policies are not good enough to work without problems and the focus is
now to make the sysadmin role work correctly and then work more on the other
roles (or something like that). 

Next time I will encounter a crash or a bug, I will first test it without
selinux, to make sure is not because of the confinement.

Is there anything useful I can provide for the crash in this instance? Is there
a Selinux bugzilla group that would maybe be more interested?
