My clue was the list of dependencies in the reportbug boilerplate of 
#972218:

…
ii  libtry-tiny-perl                          0.30-1
ii  perl-modules-5.24 [liblocale-codes-perl]  5.24.1-3+deb9u5
ii  sane-utils                                1.0.31-2

liblocale-codes-perl is provided by perl-modules-5.24. That's 
oldstable and perhaps an *unused* leftover from an upgrade.

My guess was that gscan2pdf misses a dependency on `perl' (missing in 
the reportbug's list). perl would bring suitable perl-modules-x.yy 
package that is actually in the search path (@INC) and provides 
Locale::Language.

However, libtry-tiny-perl has a dependency on `perl', so while I still 
think that gscan2pdf needs to depend on `perl', I don't understand how 
missing that would lead to the situation in the bug report.


Confused,
