What are the steps to reproduce this issue? I suppose it's happening when exiting from fullscreen in youtube?

Comment 3 2018-02-28 01:56:43 PST
Yes, was on youtube with MSE activated. Will search for a way to reproduce.

Comment 4 2018-02-28 02:03:11 PST
Here it works well with webkitgtk 2.19.91 in Ephy TP.

Comment 5 2018-02-28 02:03:54 PST
And also with WebKit ToT and MSE enabled in MiniBrowser.

I don't think you can expect a reproducer for a crash like this. Most of our crashes are not reproducible.

Closing then :)

Comment 8 2018-02-28 10:56:08 PST
We have two high-quality backtraces, one taken with 2.19.91, so we know this is still broken. I think it's great that we have a good bug report for a crash that is difficult to reproduce; that's the only way we can fix these issues. Reopening.
