Crash when mms contains unsupported content type
Crash when mms contains unsupported content type

Bug 5479474
Instead of crashing when an mms message contains an unsupported content
type, silently replace that part of the slideshow with empty text. I would
have added a string that says why that part isn't shown, but it's too late
for new strings.
