Description Max Rydahl Andersen CLA 2014-04-13 02:30:31 EDT 
Tried using nightly build on 2014-04-13 and enabling dark theme and I got a "widget disposed" error.

Here is the stack trace:

Comment 1 Max Rydahl Andersen CLA 2014-04-13 02:33:06 EDT 
note that after this error occurs changing to any theme fails with same error.
Comment 2 Max Rydahl Andersen CLA 2014-04-13 02:39:32 EDT 
after restart the theme is enabled but then trying to switch back again it fails..thus I've changed the title to be about switching in general.


btw. the font colors of editors are very dark even when dark theme making it barely readable - not sure if that is a separate bug or caused by this bug.
