Comment 2 carion.nicolas 2016-09-04 11:52:55 UTC

I think bug actually occured as follows : I moved the clip from track 1 to track 2, then tried to move it back to 1 using ctrl+z and it crashed. Note that the clip was tightly inserted between two other clips, so it fitted just perfectly between the two (making it somewhat difficult to put it back on track 1 by hand).

The backtrace is quite lengthy, the segfault occured in thread 1. Notice that in the backtrace that the "this" object of the track is "0x0"

Thanks for the infos & backtrace. I could reproduce, it happens on grouped clips, will investigate
