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....
