SUMMARY
In the tab title format, '%n' is used as a placeholder for the name of the current program. With konsole 22.07.80, it is shown as a literal '%n' in the tab title, instead of being replaced with the appropriate string.

STEPS TO REPRODUCE
1. Make sure the tab title format (right-click on tab, configure) is set to '%d : %n' (without quotes)
2. Open a tab (so that the tabbar is shown)

OBSERVED RESULTS
Tab title is shown as <name of directory> : %n (i.e. the %n placeholder is not actually replaced with anything)

EXPECTED RESULTS
Tab title should be <name of directory> : <name of program> (e.g. '~ : bash')
