Thank you for the suggested patch. The change to line 430 of Devel::NYTProf::FileInfo has restored functionality to nytprofhtml with some warnings about uninitialized values. I treasure your wild guesses.

What is $self->profile and what could cause it to be undef? Is it the result of profiling a statement, or a subroutine? What do you think my usage of is seriously wrong, Perl or NYTProf? I have no problem with the module that's being profiled, or scripts that use it, or with commandline usage. I'm not doing anything unusual with NYTProf either.

Here are those warnings:
