Could you please share an example .blend file that we can use to reproduce the bug?

Here is Blend and Video file used ... tracking_test.blend VID_20181205_105136.mp4
However i have tried several times with clean blend and different video file - same result, can delete one or two curves max then freeze - crash.

Ohhh really weird, just found pattern:

When i open directly file tracking_test.blend - looks like everything is fine , can delete without crash
First open blender and from splash menu open last used - in my case tracking_test.blend and problem appears.

Really strange, crash happens when you first open blender then file, and works fine when you directly open file from nautilus in my case.

Hmmm, I can't reproduce it right now. Maybe I just don't know exactly what I'm doing. Could you make a short video in which you show exactly what you do to make it crash?

I can reproduce this as well. I open the tracking_test.blend file from above, select any Marker, hit X to delete: -> CRASH.
Here's the log from --debug-all: http://pasteall.org/1402918
