If one can provide the fix in our package, I don't see the reason not to provide it.What is weird is why upstream did not push a new version out with this (and other) bugfixes in the meantime.
In order to provide even more bleeding-edge binaries of texlive-bin I
am thinking about creating a texlive-bin-dev package, especially to
provide bugfixes like  and .
However, how to download the source code? One way would be to checkout
the full SVN repository (using default pacman svn checkout), but that
takes up a lot of space and bandwidth (initially).
