Do you mean the pcre2 migration, or some other transition? (re2 is also 
a package that exists, but it seems to be at the same version in testing 
and unstable)

This should be fixed by a binNMU rather than by source changes. The 
upstream source handles either the old or new pcre2, but it can only 
handle the new error codes from the updated pcre2 if it was built 
against a suitable pcre2 version.

If we need to do a sourceful upload of glib2.0 for some other reason, 
then that would also resolve this automatically, but a binNMU would 
migrate sooner than a sourceful upload.
