Public bug reported:
pyparsing 2.0.0 and 1.5.7 have a serious bug breaking any forward grammar:
http://sourceforge.net/p/pyparsing/bugs/67/
this is fixed in 2.0.1 with a very small patch, but it is complicated
due to a split into two source packages which happened in 2.0.0 and
1.5.7, the python3 source is python3-pyparsing.
in 2.0.1 this is reverted again and it is one source package again.
I contacted upstream and they said this is intended to stay this way now.
To resolve the issue we have two options:
patch 1.5.7 and 2.0.0, easy but programs that check for version numbers to
avoid the bug will not accept the package.
This is the case e.g. with matplotlib 1.3, I have filed a patch which was
accepted but there might be more cases out there.
update pyparsing to 2.0.1 which is a bit more involved thus the FFe request.
pyparsing will again provide python-pyparsing and python3-pyparsing
python3-pyparsing(binary) from python3-pyparsing(source) will be obsoleted by
pyparsing 2.0.1 so no upgrade issues should occur, once its published
python3-pyparsing (source) can be removed.
I have contacted the debian maintainer about this but he is *very* hard to get
a hold of, so I want to do it in ubuntu directly rather soon.
