Bug#870104: kio_http_cache_cleaner runs indefinitely after logging out of KDE

[Brice Hunt <shoalcreek5@gmail.com>]

Package: kio
Version: 5.28.0-2
Severity: normal

Dear Maintainer,

2nd or 3rd graphical logins to Plasma Desktop by various users sometimes hang in 
diverse and weird ways. Upon investigation, many processes were found to still be 
running after users log out. Further investigating, kio_http_cache_cleaner seems 
to be consistently running after a log out, causing other processes to not quit 
on logout. Killing this process would end the other processes that had remained
running, and the weird hangs never seem to happen if this process is killed 
after logging out.

I would submit a patch, but I am not sure of how sddm controls the logout to 
ensure processes are terminated appropriately.
