Bug 153566 – Cannot render images from Wikipedia

• Status: RESOLVED
• Resolution: WORKSFORME
• Component: Platform

[Debarshi Ray]

On a stock Fedora 23 x86_64 system, epiphany fails to render links like these:
https://en.wikipedia.org/wiki/Brenizer_Method#/media/File:Pomegranate_bokehrama_portrait.jpg

I get the usual "Oops! Something went wrong while displaying this page.".

Versions:
webkitgtk4-2.10.4-1.fc23.x86_64
epiphany-3.18.3-1.fc23.x86_64

[Michael Catanzaro]

Uh-oh, a crash in cross-platform graphics filters....

(In reply to comment #0)

Thanks for this bug report. I can't reproduce the problem though, same bat distro, same bat package versions. Rishi, if you still have the core dump (coredumpctl? abrt?) it would be great if you could post a 'bt full' for thread 1.

And someone with Safari should check if it crashes there.

[Debarshi Ray]

I haven't been able to reproduce with Fedora 26 so far:
epiphany-3.24.3-1.fc26.x86_64
webkitgtk4-2.16.6-1.fc26.x86_64

[Adrian Perez]

I cannot reproduce this either. I have tried the following versions:

 - WebKitGTK+ 2.16.6, Epiphany 3.24.3
 - WebKitGTK+ 2.17.91, Epiphany 3.25.90
 - WebKitGTK+ / MiniBrowser from trunk (r220984)

All the versions tried can load and display the provided URL correctly.

[Michael Catanzaro]

This bug is old, so let's assume it's fixed.
