The line raising the exception is in ruby gem rbpdf version 1.21.3 in RBPDF#putannotsobjs:
# rbpdf-1.21.3/lib/rbpdf.rb:6268
else
# internal link
l = @links[pl['txt']] # <-- l must be nil to raise the error
annots << sprintf(' /Dest [%d 0 R /XYZ 0 %.2f null]', 1 + (2 * l[0]), @pagedim[l[0]]['h'] - (l[1] * @k))
end
These lines of code will only then be crossed when multiple wiki pages should be merged into a single pdf file.
pl is a hash with content like this: {"x"=>18.062575, "y"=>37.85658333333333, "w"=>23.460075, "h"=>3.175, "txt"=>1, "opt"=>{"subtype"=>"Link"}, "numspaces"=>0}.
The 'txt' variable comes from method RBPDF#Annotation(x, y, w, h, text, opt={'Subtype'=>'Text'}, spaces=0). It gets its params from RBPDF#Link what again gets the text param meanwhile called link from RBPDF#AddLink.
