Can't seem to open a PM

[The Outrage]

So there's this PM in my inbox with a sender but no title, which means I am perfectly able to click the user's name but unable to open the PM.

Any suggestion?

EDIT:
Okay, I've figured out how to retrieve the text by downloading it as a text file, but it doesn't resolve the fact there may be a glitch in the system.

Hmmm. That's worrying. But a glitch would explain why I was unable to find some old contest PM's with addresses and such. Will look into it.
