Can't Locate Title (error trying to add Media files)

[Samer Meshreki]

comic book title:

A.D.: After Death

Trying to add a media file named Bk 1-HC.pdf when this error pops up.

If I rename the file as 1.pdf it has no problem being added to the same title.

I also have no problems adding a new cover image named Bk 1-HC.jpg.

Please advise.

Thanks,
Sam

A little more information. The following names work:

1.pdf
1-HC.pdf
Bk 1-A.pdf
FCBD 2013.pdf
1-HC-2.pdf

These names do NOT work:

Bk 1-HC.pdf
Dlx 1-HC.pdf

Just ending in HC works successfully.

But if there is a <space> in the name AND it ends with HC, it doesn't work.
