I'm observing the same symptom with blender 2.82.a+dfsg-1+b3 on Debian testing.
blender:
Installed: 2.82.a+dfsg-1+b3

I installed the coredumpctl package and managed to get something like a partial stack trace.

The crash happened every time I tried adding a movie strip.
Details about the movie strip:

In the meantime I'm working around this by running Blender downloaded directly from
