Sample file with long Title attribute

When printing, Evince creates print job names using the title of the PDF being printed. This job name can however be too long, and in such a case CUPS refuses to print it. The attached file can be used to reproduce the problem, which happens to me on Ubuntu Trusty with Evince 3.10.3 and CUPS 1.7.2.

The CUPS error log says:

RFC 2911 section 4.1.2 says:
   The
   'name' attribute syntax is essentially the same as 'text', including
   the REQUIRED support of UTF-8 except that the sequence of characters
   is limited so that its encoded form MUST NOT exceed 255 (MAX) octets.

https://tools.ietf.org/html/rfc2911#section-4.1.2

So I think Evince should truncate the job-name to be compliant with the RFC.
