I've seen another possible QT race condition ever since I moved to 0.23. 
For every theme I have tried, if I click back through screens too fast, 
every now and then, the screen information will disappear and all you 
get is a blank screen with the theme wallpaper.

This is most apparent in mythvideo where if I click through to a folder 
full of video files and then select a particular video file (popping up 
the page showing the video details with the play button). If I then 
press the back button too fast, the page it sends me to is completely 
empty. i.e., no video file icons are visible.

the solution for this is either to restart mythfrontend (I have a 
kill/resume process linked to my remote's off button just for this) or 
to press enter to go to the video information screen (which will not be 
shown. i.e., you will see a blank screen) and then press okay to play 
the video. the video will play and returning from the video will redraw 
the screens fine.

from my limited testing, this happens if I click back too quickly. If I 
take my time, it seems to be better. but this is very unscientific test.

I read a posting about this same behaviour quite a few months ago (with 
relation to the same theme I use most of the time. The blue-abstract 
theme). but I did not remember seeing any solutions posted.
