The display code which renders this doesn't know anything about the
meaning of the extensions, it only cares about the characters it needs
to display.  So if image-file extensions tend to cause this, it's
because of the characters that are part of the extensions, or maybe
because having an image file visited by the buffer affects the mode
line in some other way that causes this issue.

Maybe someone else can reproduce this?
