[Gnump3d-users] how to find source of warnings

[Mezlo]

Hey all,

I am running GNUMP3d 2.9.4 on a CentOS 3.5 linux system with Perl 5.8.0.
When I run gnump3d-index, I get about 20 lines of the following warning:

"Use of uninitialized value in numeric lt (<) at /usr/bin/gnump3d-index 
line 392."

While everything seems to work fine, I want to know if there is any way to 
determine which songs are causing the warnings and why?
