Dear maintainers,

eventually I have found the reasons why the dependencies on libharfbuzz0b 
and libharfbuzz-gobject0 are missing.  Since there are two different 
reasons, I am cloning this bug ticket, so that the two issues can be dealt 
with independently from one another.

1. Starting with harfbuzz/5.1.0-1, HarfBuzz-0.0.typelib as well as
    HarfBuzz-0.0.gir do no longer reference libharfbuzz.so.0 although
    449 of the 490 symbols are compiled into libharfbuzz.so.0 and just
    the other 41 symbols are compiled into libharfbuzz-gobject.so.0.
    I have lowered the severity because libharfbuzz-gobject.so.0 depends
    on libharfbuzz.so.0 and once when dh_girepository is fixed, a rebuilt
    gir1.2-harfbuzz-0.0 would automatically depend on libharfbuzz-gobject0
    at least, and that would pull in libharfbuzz0b in turn.

2. dh_girepository does not fetch the 41 symbols from HarfBuzz-0.0.gir
    that are compiled into libharfbuzz-gobject.so.0.  I have attached a
    small patch for it, so that the missing symbols are also dumped into
    the dummy C file that is temporarily generated and compiled for
    dh_shlibdeps.
    This updated version of dh_girepository would also find another 245
    symbols in Gio-2.0.gir for instance.

Best regards,

Thomas Uhle
