This is probably due to a documentation build failure as below: Output written on darcs.dvi (228 pages, 826908 bytes). Transcript written on darcs.log. --- warning --- Can't find/open file `tex4ht.env | .tex4ht' --- error --- Illegal storage address
The program segfaults when it can't find tex4ht. Not sure why it segfaults or why it can't find that file... investigating.
