The documentation of File::Find says:

WARNINGS

If you run your program with the -w switch, or if you use the warnings pragma, File::Find will report warnings for several weird situations. You can disable these warnings by putting the statement

    no warnings 'File::Find';

in the appropriate scope. See perllexwarn for more info about lexical warnings.

Perhaps that is the "cause" of your weird error messages.
