A couple of errors (was Re: timelines from GEDCOM files)

In playing with the program, I am getting the following:

Can't call method "name" on an undefined value at C:/Perl/site/lib/HTML/Timeline
.pm line 280, <GEN0> line 22085.

The Gedcom line in question is an unremarkable 
0 @I1548@ INDI
1 NAME Samuel /Washington/
2 SURN Washington
2 GIVN Samuel
1 SEX M

with the blowup line, 22085, being the GIVN Samuel

Could it be that it's just too big?  Any ideas?

I had another error, 
Test.ged:26: EMAIL is not a sub-item of SUBM
Cannot validate file: Test.ged at timeline.pl line 42

caused by the email field that PAF inserted into the file.

Not a biggie, but perhaps the next iteration might ignore email.
