I'm using the apex InputFile standard component to allow users to attach images to one of my custom objects.

There seems to be a limit on the file name size, but I can't find anything in the docs or force sites to confirm this.

If the file name is greater than 81 characters, I get redirected to the salesforce "an error has occurred" page, but I don't get any warning emails etc., nor can I trap this error as it is happening before hitting my controller. 

Has anyone else seen this?
