Description Michael Catanzaro 2015-09-25 13:35:37 PDT
From the downstream report:

"Right-click new tab on a bugzilla.redhat.com bug.

From now on, starting epiphany (which remembers which tabs are open) crashes it immediately."

I couldn't reproduce with my development build. Full backtrace downstream.

Truncated backtrace:

Apparently this can be reproduced by visiting extensions.gnome.org (so a site that attempts to load a NPAPI plugin) in Wayland.
Comment 3 Michael Catanzaro 2015-09-25 14:13:47 PDT
Another user reports: "Started epiphany, tried to reload failed tab."

Yoon, this is the bug you looked at in Gothenburg.

I could not reproduce this crash in my environment.
I launched the minibrowser in the Weston compositor and visit there,
but it loads the page without crash with a warning message: "we cannot detect a running copy of GNOME..".
Not sure how I can reproduce it.

btw, I changed my distro to fedora as you suggested. :)

Not sure either, but when you looked at it last time, you said it was a very simple problem. I was quite tired at the time and not paying too much attention; maybe you were too. :p

Well you did keep complaining about your previous distro. :)

I had a similar problem with epiphany 3.18.0 at app start.

Terminal output: 

Gdk-CRITICAL **: gdk_window_create_similar_surface: assertion 'GDK_IS_WINDOW (window)' failed
