Exif: Failed to set text from markup due to error parsing markup

[David Hunt]

If any of my exif data has a & in it then it is not displayed properly and there is an error on the console every time it needs to be rendered

(ART:25446): Gtk-WARNING **: 09:43:03.399: Failed to set text from markup due to error parsing markup: Error on line 1: Entity did not end with a semicolon; most likely you used an ampersand character without intending to start an entity — escape ampersand as &

‌

This is occurring as it is trying to render this field with markup enabled. I don’t believe markup is allowed in exif (I could be wrong) so I think this should just be rendered as text.

I’ve attached a patch to fix this issue.
