Backtrace stopped: previous frame identical to this frame (corrupt stack?)

---

part of gdb session...

for reproduction.

1) load video
2) seek to some frame by setting there playhead/cursor on timeline
3) apply edit > cut (x) {blade cut}
4) attach iris square transition from video > attach transition menu.
5) set in point at very same frame
6) move cursor a bit after transition bar ended..
7) set out point
8) use edit>add silence..

in my case it crashes....
