Description Daniel Klein 2016-05-11 02:02:53 UTC

Reproduce:

1. New proj - 3video+2audio, add clip to bin and then to timeline (on the first track).

2. Delete 2 last tracks [audio].

3. Cut clip on 1st track [5-6 cuts].

4. Mouse-drag one of the cuts from 1st track to 2nd. Works fine.

5. Select several cuts and drag to 2nd track - timeline shows them on 2nd track but actualy places them on 3rd track -

A. Show/hide 2nd/3rd track [i.e. clips appear on 2nd track - hide that track but playback still show them; hide 3rd track - playback is black], or -

B. Save-quit-reopen: the clips that appeared on the 2nd track are now on 3rd.

gdb shows no extra messages (other than threads..).

Ok, this happens every time - i.e. you can skip stage (2) in my instructions.

Comment 2 Daniel Klein 2016-05-11 17:04:56 UTC

If I reopen the project, I see the clips on 3rd track.
When I move them to 2nd track, they appear to be moved there, but actualy placed on 1st....

Thanks for your report. Should hopefully be fixed now in git. Please test again when the updated package is available on our PPA (should be in a few hours).

Comment 6 Daniel Klein 2016-05-13 22:37:58 UTC

The fix has also resolved some other issues, with dragging several selected clips (had some "track mismatch" crushes sometimes). Nice. Much appreciated.
