Description Anderson Medeiros Gomes 2015-09-19 16:00:04 UTC 
Gwenview is unable to load some images I have saved on my computer. However, Konqueror can open them.

This is an example image: http://www.luagge.com.br/imobiliar/Fotos/284/00000284AA_fa_0.jpg . The console display these messages when I try to open it:

$ gwenview --version
org.kde.gwenview 15.08.0
$ gwenview 'http://www.luagge.com.br/imobiliar/Fotos/284/00000284AA_fa_0.jpg'
QImageReader::read() using format hint "jpg" failed: "Unknown error"
A bad Qt image decoder moved the buffer to 69104 in a call to canRead()! Rewinding.
Image format is actually "jpeg" not "jpg"

There is a downstream bug report here: https://bugzilla.redhat.com/show_bug.cgi?id=1257632

Also, there is a question of an Arch user here: https://www.reddit.com/r/kde/comments/3l7l75/gwenview_1508_on_plasma_5arch_fails_to_open_jpgs/

1. Open the referenced image using gwenview.
