Bug 512618

SUMMARY
Executable titles in colour blocks fail to render, and log is flooded with "Unable to assign [undefined] to QString" message.

STEPS TO REPRODUCE
1. Open kjournald.

OBSERVED RESULT
Journald log flooded with:

kjournaldbrowser[32052]: qrc:/qt/qml/org/kde/kjournaldbrowser/LogView.qml:204:25: Unable to assign [undefined] to QString

I believe this is related to Colorize->Executable setting being turned on. 

Some of the colour blocks do not have the title showing the executable path in the top right. I believe this is the cause of the failed assignment error.

EXPECTED RESULT
Browser works without error.
