Ok, great. If it was intentional, it's not a bug. Well, unless yiou forget to 
uncomment it for release, anyway ;-)

I was about to say that there was another bug in piave, where a new scenelist 
doesn't get displayed until at least one seek command has been issued... but 
then I remembered that kdenlive caches the scenelist until a seek command is 
issued. Oops! The fix is going to be slightly tricky, since I have to make 
sure the scenelist gets sent when it needs to be, but not when it should be 
held back...

(The reason for this problem - clicking on a clip in the project list should 
automatically display it in the clip monitor, currently you have to seek 
before you see anything.)

Cheers,
Jason
