Bug#1091683: spamassassin: Multiple warnings "Use of uninitialized value $_"

[Timo van Roermund]

According to the upstream bug report, the issue was already resolved and 
the fix should be part of the next release.

The patch can be found here:
https://svn.apache.org/viewvc/spamassassin/trunk/lib/Mail/SpamAssassin/Plugin/PDFInfo.pm?r1=1919365&r2=1919364&pathrev=1919365

It is unclear (to me) when this next version of SpamAssassin will be 
released. I'll therefore apply this patch locally and monitor if the 
issue doesn't resurface.
