web-doc (again-again)

[Rune Zedeler]

Okay, installed lily with kpathsea.
Web-doc still doesn't build, though.
After producing loads and loads of warnings like

Calculating column positions... programming error: Molecule::add_at_edge: 
adding empty molecule. (Continuing; cross thumbs)
programming error: Molecule::add_at_edge: adding empty molecule. (Continuing; 
cross thumbs)programming error: Molecule::add_at_edge: adding empty molecule. 
(Continuing; cross thumbs)
programming error: Improbable offset for translation: setting to zero 
(Continuing; cross thumbs)

it finally breaks with

And a nice core dump appears :(

ly2dvi'ing the autocreated ly-files by hand causes no trouble - but still the 
web-doc fails.
CHANGES, DEDICATION, NEWS, hacking and index are there (.html) but nothing else.
