See https://en.wikipedia.org/wiki/Hermann_M%C3%BCller_%28politician%29 for example; found in Chrome 27 on a Mac. In Safari 6.0.5 it displays differently (a large space appears, rather than a missing icon signifier) but is still broken. Not replicatable in Firefox 21.0/Windows 7.
It's inserting a thumbnail image at fixed 200px width. <img resource="./File:Hermann_Müller.ogg" src="http://upload.wikimedia.org/wikipedia/commons/d/d3/Hermann_M%C3%BCller.ogg" width="200" data-parsoid="{"a":{"resource":"./File:Hermann_Müller.ogg"},"sa":{"resource":":File:Hermann Müller.ogg"}}">
This is now fixed in production for Parsoid (and so for VisualEditor). Sorry for the bug!

Seems to me, this is still buggy ! Have tried the following code at http://parsoid.wmflabs.org/_rtform/: [[File:La_Marseillaise.ogg]] This gives: <img resource="./File:La_Marseillaise.ogg" src="//upload.wikimedia.org/wikipedia/commons/3/30/La_Marseillaise.ogg" data-parsoid="{"a":{"resource":"./File:La_Marseillaise.ogg"},"sa":{"resource":"File:La_Marseillaise.ogg"}}" width="200">
The original bug was rendering of [[:Media:Hermann Müller.ogg]]. The rendering of [[File:Hermann Müller.ogg]]/[[File:La_Marseillaise.ogg]] is a different problem, as that renders as a player in source editor. There are some underlying problems in Parsiod and even the mw API if I am understanding bug 49896 correctly.
