Summary0001235: Crash after adding new track and then moving clip to
DescriptionI just experienced a crash where I added a new video track 3 and then moved a color clip from track 2 to 3. Hopefully the backtrace info below is useful.

I have kdenlive tarball 0.7.6 and mlt from SVN of a week or so ago.
Steps To ReproduceI could only reproduce on the video I was working on at the moment.
1) vid clip on track 1 that had dissolve with track 3
2) vid clip on track 2 that had dissolve with track 3
3) color clip on track 3
4) inserted track 3 above existing track 3
5) moved color clip up to new track 3 and got crash

Tried this several times and got same crash.
I worked around this by moving removing dissolve with track references in steps 1 and 2 and moving color clip to track 2 temporarily. Then I inserted the new track and all was okay.

Can you still reproduce it? If yes, it would be helpful to have the video (or poject) you were working on.

Yes I can still crash it. I'll attach some backtrace info (but probably not useful) and the project file.

Steps: select track 3 then use menus to insert a video track below Video 392)

I should note that this is now on.
Kdenlive 0.8
MLT melt 0.7.2
Frei0r GIT 20110428 (i think =1.3)
Fedora 14 Kde 4.6.3

The crash seems to happen somewhere in the Oxygen decoration. I think that this is a KDE / Qt bug. Which Qt version do you have?

qt = 4.7.2 from fedora updates
