            Bug ID: 405444
           Summary: ksplashqml hits its hard timeout of 30 seconds because
                    of failing qdbus call kinit
           Product: ksplash
           Version: 5.14.5
          Platform: Debian testing
                OS: Linux

ksplashqml: Retry in start script if dbus interface is not yet up.

When /usr/bin/startkde starts it first executes ksplashqml around line 134.
Later around line 297 is a call "qdbus ... kinit" to increase the
stage in ksplashqml.

Unfortunately it looks like on fast enough systems the qdbus call is faster
reached as ksplashqml has opened the dbus interface.

This results in the message in .xsession-errors:

    Cannot find 'org.kde.KSplash.setStage' in object /KSplash at
org.kde.KSplash

Therefore ksplashqml seems to never reach setStage(6) to finish
its execution and therefore runs into the hard limit of 30 seconds.

Attached patch tries to retry the qdus call when it returns not success.
Unfortunately the overhead of the loop might be already enough to have
the dbus interface already up, because I did never see the logging when
doing a retry.
