Seems like a matter of setting HOME=`pwd`

This won't fix the bug, merely let official buildds proceed.  Every single
package is supposed to be autobuildable, not merely arch-dependent ones.

Your sponsor did, by hand, on i386.

It hasn't been built in a controlled environment anywhere yet.  You can
approximate one using pbuilder.

You shouldn't assume any directory outside of your build path and /tmp/ is
writeable.  Here, the bug appears to be in unoconv (if the report is
correct, which I did not check), yet it can be trivially worked around by
setting $HOME.

Every package must be fully buildable from source -- as in, every binary
package must be reproduceable depending on nothing you did not explicitely
declare in Build-Depends (-Indep, -Arch) and build-essential.

pbuilder is not 100% identical but should be good enough.  And a FTBFS in
pbuilder is bad enough.

Hope this helps.
