The temporary logfile this generates to determine the textwidth
includes the following line:
\...@matrix@numberofcolumns=\count106
This is erroneously picked up by the regular expression which searches
for columns=[a number] here:
1750 m = re.search ('columns=([0-9.]*)', parameter_string)
1751 if m:
1752 columns = int (m.group (1))
The search is greedy, but it can't read `\count106' and convert it to
an integer.
The simplest solution would be to change the regexp to the following:
1750 m = re.search ('columns=([0-9.]+)', parameter_string)
This will ensure the search tries to match at least one digit directly
after the equal sign.
Alternatively re.match could be used as a less greedy search, but I'm
not that familiar with lilypond-book and its interaction with LaTeX to
know whether this is desirable, since it would only match strings
which begin with `columns'.

Neil
