Thank you. My full document also builds now with the above environment. The
strange thing is that, just as you noted, even though all texlive-hyphen-{a
lot of european languages} are all installed my pdflatex outputs the
following:
Package babel Warning: No hyphenation patterns were preloaded for
> (babel) the language `Swedish' into the format.
> (babel) Please, configure your TeX system to add them and
> (babel) rebuild the format. Now I will use the patterns
> (babel) preloaded for \language=0 instead on input line 49.

And in the document hyphenation is very much broken, either not breaking
words at all or breaking in the wrong places.
