Comment 2 for bug 727070

After submitting the bug, I immediately logged out and logged in and now the window title bars are back.
But, unfortunately now there is another problem - the whole appearance has changed.
The theme I use (Dust) is only visible in the window borders and titlebar, which the rest of the desktop is unthemed, and when I go to Appearance it says that I have selected a custom theme.
The desktop background is normal and the theme of the panels works for a left panel, so only the top panel is not themed properly.

So somehow the whole desktop has decided by itself that it should look like something else.
