Sentry Crash Report:

Description Elias Probst 2014-10-08 11:38:21 UTC 
Running KF5/P5 from git + Qt 5.4.0 alpha.

Requested gwenview "git log -1":
commit 4eaf0f464ebb513f8fa3d5a531e7a7285f0528b4
Author: Luca Beltrame <lbeltrame@kde.org>
Date:   Wed Oct 8 07:34:31 2014 +0200

    Use -qwindowtitle instead of the no longer existing -caption

When trying to open a WebP image via http:// (e.g. https://www.gstatic.com/webp/gallery3/2_webp_ll.webp), gwenview crashes after startup (the window shows up for a brief moment).

Downloading the file and opening locally works as expected and shows the message
Loading 2_webp_ll.webp failed
Gwenview cannot display documents of type image/x-webp.
… as I built my system without WebP support.

Application: Gwenview (gwenview), signal: Segmentation fault
