Go to https://fr.wikivoyage.org/wiki/Lac-M%C3%A9gantic (or [[voy:Mégantic]] en anglais) and click on that big {{pagebanner}} image at the top of the page... the one with the mountain. "Loading image..." "Image unavailable." (View image in its original context.) Click the fool thing and end up at [[Image:Lac-Mégantic banner.jpg]], which evidently does not exist as the Unicode is broken. There's a [[Image:Lac-Mégantic banner.jpg]] on commons: but MultimediaViewer doesn't know that because it doesn't handle Unicode properly. I'm running the Firefox 30 which came with a 1337 pir8 copy of Ubuntu 14 (amd64) and haven't tried any browser comparisons to see if this happens anywhere else. Is anyone else seeing this on images with Unicode filenames?
Works for me (the lightbox as well as both file description page links). Ubuntu 14.04, Chrome 37 and Firefox 32.
No problem in Firefox 31 on Fedora 20 either with the first link in comment 0
It looks like this odd behaviour is caused by Greasedlightbox, a Firefox extension which pops up an image viewer which looks very much like the MultimediaViewer but is not. That browser extension is either incompatible with MediaWiki or with MultimediaViewer, remove it and the issues go away.
