Use of uninitialized value in numeric gt (>)

[eturconi]

Hi guys,
Where i try to export a F.A.Q to pdf I receive the following error and the result is that the images are not attached into the file
Use of uninitialized value in numeric gt (>) at E:/OTRS/StrawberryPerl/perl/site/lib/Font/TTF/Glyph.pm line 255., referer: http://tts/otrs/public.pl?Action=PublicFAQZoom;ItemID=6

Is there anyone that could help me to fix that?
Regards
Emanuele

Images would not be exported to PDF. So this is no error
