[Debian-med-packaging] Bug#836230: Bug#836230: genometools: FTBFS in testing (a2x: ERROR: "xsltproc" returned non-zero exit status 6)

Wed Aug 31 22:49:12 UTC 2016

This is my build history:

Status: successful  genometools_1.5.9+ds-2_amd64-20160811T2351Z
Status: successful  genometools_1.5.9+ds-2_amd64-20160816T1151Z

Status: failed      genometools_1.5.9+ds-2_amd64-20160831T144105Z
Status: failed      genometools_1.5.9+ds-2_amd64-20160831T152720Z

All those builds were done in machines with 768 MB of RAM
(and 1GB of swap).

Why it built ok in the past and now it does not build?
