Just catched a core dump.

It's better after an upgrade, but I am still seeing core dumps.

These crashes seem random. Does your system pass memtest?

> Does your system pass memtest?

Did run for about 2h with 0 errors, I aborted it since I had to get back to work :)

Since the upgrade to 40.0 "only" one tab crashes and not the whole browser, but it even seems more often.

https://github.com/Igalia/WPEBackend-fdo/issues/145 looks relevant.

I can confirm that I see the crash (pretty often), when clicking "back" before a page is fully loaded.

just for the record ... the initial warnings/errors still show up

First the crash regarding "wl_proxy_marshal_constructor ". I see this crashes on one of my ThinkPads, nearly identical hardware. The affected X220 runs Wayland:

The other one is a T420 which runs X11 and is not affect by this issue.

@Tobias Munk:
As far as I know Epiphany tries to load and then use these spell checking libraries. Likely with dlopen() and that shouldn't be a reason to worry, these are not hard dependencies. You can get rid of the messages by installing all of them. They shall not have anything to do with the crash!

Regarding the DBus messages I don't have a clue. But I see them also.

Maybe we have a fix?

Maybe we can use that patches from 1.10 branch?
https://github.com/Igalia/WPEBackend-fdo/commits/wpebackend-fdo-1.10

Sorry. Accidentally clicked to early! I think we can close this issue now.
Maybe there is another new issue with libgstgl but I need to collect first data wether it depends on i915, wayland and gstreamer-vaapi.
