This is likely the bug I found and fixed libregexp-pattern-license-perl 
later yesterday: licensecheck <= 3.2.6 relied on not-yet-documented 
hints in libregexp-pattern-license-perl which was partly broken¹ and 
when fixed broke that old (mis)use of it.

I tested various combinations of old app with new lib and vice versa and 
thought I had dealt with it, but evidently not: Ysterday I added a hint 
that recent libregexp-pattern-license-perl breaks old licensecheck.


Thanks for investigating,

¹ Regexp::Pattern::License contains patterns for common "traits", e.g. 
grant prefix "...is licensed under" and exception prefix "In addition to 
the permissions in...".  When exception traits were introduced they were 
wrongly tagged as type:trait:grant:prefix, and when Licensecheck began 
using then it overconfidently didn't account for a possible empty result 
when looking up tags.  So when I corrected the tags as 
type:trait:exception:prefix, licensecheck would blew up when used with 
newer Regexp::Pattern::License, instead of just fail to detect 
exceptions as expected.
