Hello,

we're experiencing problems with printing patroncards from Koha. The final
result depends on used browser, for instance in opera I'm able to download
blank pdf, however, in firefox I end up with "Not found. The document has moved
here." error(under "here" link is nothing->nothing happens). 

We use self-build Koha with several changes from upstream, but we haven't
edited this fuction.

The logged errors are as following:

manage.pl: CGI::param called in list context from package Template::Document
line 57, this can lead to vulnerabilities. See the warning in "Fetching the
value or values of a single named parameter" at /usr/share/perl5/CGI.pm line
436.

create-pdf.pl: Use of uninitialized value in substitution iterator at
/usr/share/koha/lib/C4/Patroncards/Patroncard.pm line 233.

create-pdf.pl: Use of uninitialized value $string_width in addition (+) at
/usr/share/koha/lib/C4/Patroncards/Patroncard.pm line 256.

Thanks for helping
Martin
