When exporting an issue to PDF we are getting a string to integer error

TypeError (can't convert String into Integer):
lib/redmine/export/pdf.rb:246:in `block in issue_to_pdf

I've tracked the problem down to the MultiCell command, if I change it to Cell then it works OK but only prints on a single line.

After a little digging around I found the MutliCell command in the fpdf.rb file. I tracked the problem down to the following command

l=l+cw[c⁰]

I'm no Ruby developer so I wasn't sure of the fix but I could understand what it was trying to do, so I change the line to the following

l=l+500

I appreciate this will not fill the width of the document but its pretty close.

Is there a "proper" fix?
