demostrate .xls chart failure

See the attached .gnumeric file.
Desired behavior: chart is of size 600 x 300.
.
Then ssconvert graph-fail2.gnumeric graph-fail2.xls
Open the .xls file.  Observe chart size 722 x 4344.  Not good.

I conjecture this is an import issue rather than an export
issue, since openoffice can read the .xls file;  the result
is not pretty but it's not nearly so bad.

The same symptoms were observed using 1.12.22 as distributed
by ubuntu.  However, this report is based on the latest version,
freshly compiled from a fresh git-pull:
