Renaming a blogpost to use an illegal character causes exception instead of a simple error/try-again page

It seems that the validation code that we use for pagename-validation has not been applied to blogposts when editing blogposts was implemented in 2.7 (or was it 2.6?)

I get this exception if I add hyphens or slashes:
