Review request for Dolphin.


Repository: kde-baseapps


Description
-------

The summary says it all - instead of emitting a signal with an empty QSet as its argument and printing a warning message, just use the roles that really have changed. The message is not really useful for users who read Dolphin's output in Konsole or .xsession-errors and can be confusing, see https://bugs.kde.org/show_bug.cgi?id=336174

In 4.13, I would prefer not to change this (even though it seems very unlikely that it causes problems), and only remove the warning output.

Testing
-------

Unit tests work fine. Tried to switch previews on/off and added/removed columns in Details View. Everything seems to work fine.


Thanks,

Frank Reininghaus
