Comment 6 for bug 1291939

I have also a theme problem.
After testing environment kubuntu I removed kubuntu desktop because I prefer unity .
I use applications like gwenview using KDE dependencies in ubuntu desktop unity .
I uninstalled KDE , but since I have problems in my display unity with the environment theme ambiance was certainly modified by installing KDE:
- The menu at the top right (to stop the pc or close the session)have the text black on a dark background
-The Icons that represent files in file explorer are those of kde .

Here is a link to the screenshot of my screen unity copy:

I tried to reapply the ambiance default theme with Unity Tweak Tool but it changes nothing.

Can you help me to correctly reset the ambiance theme of unity .
