[Gnump3d-users] "isn't numeric in numeric comparison" error

[Brandon Kuczenski]

Hey folks -- love the software.

I'm running gnump3d v2.9.3 on FreeBSD 4.11 with perl 5.8.6.

My error.log is filled with statements like:

Argument "They Might Be Giants - The Guitar" isn't numeric in numeric 
comparison (<=>) at 
/usr/local/lib/perl5/site_perl/5.8.6/gnump3d/sorting.pm line 119.

My log is filled with them.  I've seen other people post excerpts from 
their logs that contain the same phrases, but I haven't seen anyone ask 
specifically about them, or anyone else suggest specifically how to fix 
it.  I would still like to see legitimate errors, so I don't want to set 
/dev/null as my error log file.

Any solutions on record?

Thanks in advance,
Brandon
