            Bug ID: 423119
           Summary: dcopserver doesn't launch with XDG_RUNTIME_DIR set
           Product: kde
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: goeran at uddeborg.se
  Target Milestone: ---

SUMMARY
After upgrading my Fedora system, ksensors stopped working.  Some investigation
done in a Fedora bug (https://bugzilla.redhat.com/show_bug.cgi?id=1768193)
figured out the underlying reason is that dcopserver doesn't start as long as
XDG_RUNTIME_DIR, which it is by default.  Since this appears to me to be an
upstreams bug, I'm reporting it here.


STEPS TO REPRODUCE
1. ksensors


OBSERVED RESULT
ICE Connection rejected!

DCOPClient::attachInternal. Attach failed Authentication Rejected, reason :
None of the authentication protocols specified are supported and host-based
authentication failed
ICE Connection rejected!

DCOPClient::attachInternal. Attach failed Authentication Rejected, reason :
None of the authentication protocols specified are supported and host-based
authentication failed
DCOPServer self-test failed.
kdeinit: DCOPServer could not be started, aborting.


EXPECTED RESULT
A ksensors icon in the status field of the panel.


SOFTWARE/OS VERSIONS
I'm not sure where to find "About System", but this is on a Fedora 32 system
with these RPMs:

    ksensors-0.7.3-45.fc32.x86_64
    kdelibs3-3.5.10-103.fc32.x86_64


ADDITIONAL INFORMATION
Running

    env -u XDG_RUNTIME_DIR ksensors

seems to work as expected.
