text corruption in ubuntu package version

[Kevin Horan]

When running the command "obabel -L descriptors", the output contains garbage characters:
# obabel -L descriptors
abonds `�V
atoms
bonds p�
           cansmi Canonical SMILES
cansmiNS Canonical SMILES without isotopes or stereo
    ,S
formula Chemical formula
HBA1 Number of Hydrogen Bond Acceptors 1 (JoelLib)
HBA2 Number of Hydrogen Bond Acceptors 2 (JoelLib)
HBD Number of Hydrogen Bond Donors (JoelLib)
InChI IUPAC InChI identifier
InChIKey InChIKey
abonds InChIKey InChIKey
logP octanol/water partition coefficient
MP Melting point
MR molar refractivity
MW Molecular Weight filter
nF Number of Fluorine Atoms
s SMARTS filter
sbonds SmartsDescriptor
smarts SMARTS filter
tbonds iptor is definable
title For comparing a molecule's title
TPSA topological polar surface area

In particular, the descriptors "cansmi", "formula", and "title" are corrupted (it appears on the line above each of these names). The corruption appears to be in the names themselves because when I use the openbabel library (C++ code) in my own application and try to use any one of these descriptors, it fails to even find the descriptor, presumably because the name does not match (due to the corruption). All other available descriptors work fine.

I have compiled the upstream source code from openbabel directly on the same machine and the output does not contain any corruption and my C++ code finds these descriptors without problem.
Here is the output with the upstream version:

# obabel -L descriptors
cansmi Canonical SMILES
cansmiNS Canonical SMILES without isotopes or stereo
formula Chemical formula
HBA1 Number of Hydrogen Bond Acceptors 1 (JoelLib)
HBA2 Number of Hydrogen Bond Acceptors 2 (JoelLib)
HBD Number of Hydrogen Bond Donors (JoelLib)
InChI IUPAC InChI identifier

logP octanol/water partition coefficient
MR molar refractivity
MW Molecular Weight filter
nF Number of Fluorine Atoms
s SMARTS filter
smarts SMARTS filter
title For comparing a molecule's title
TPSA topological polar surface area

I tried downloading the source package of openbabel from Ubuntu and building the package myself, which I was able do successfully, but the corrupt output remained.
