invalid memory access crash
after upgrading to 3.0.3 I've been getting crashes with some regularity while fast forwarding playing a video. Nowadays I run it under lldb and managed to capture one of those crashes and I have a feeling that the rest may also be related though this is the only one I've seen under lldb so far.
It looks like to be a crash in the UI, a possible use after free though I am not sure I know the code well enough to know how it got there. I remember it did crash while I was fast forwarding using the slide bar on the video window while playing a video which probably corresponds to the mouse down event in the traceback in the application run loop so at least that part of it makes sense.
I've attached the traceback let me know if there's anything else I can do for you.
