Found out how I can work around this blocking thing, run it as
   LD_ASSUME_KERNEL=2.4.1 qtvision
so my nptl is causing it (or there is a undetected deadlock somewhere)

Changing all false for true in nextButton()->setEnabled(bool); (channelscanner.cpp)
fixes it for me (I can click Next now).
Wow, it works...hmm resizing doesn't work, as soon as I resize or go to TV mode
I get 
  qtvision: Fatal IO error: client killed
Any ideas (I run 2.6.0-test11 with v4l2 bttv driver that is known to be quite slow
on resizing/moving, eg. opaque moving of xawtv makes it run the cursor behind)?
