Note that dlocate is already in reportbug's "Suggests:" list.  While I
am by no means a Python expert, it seems to me that the query_dpkg_for
function in reportbug-6.3/reportbug/utils.py already does try to go
through dlocate first, then tries again setting "use_dlocate=False" if
that fails.

Such a failure is quite likely if it's a package the user has only
just started trying out - the dlocate database is updated just once a
day, so freshly installed packages won't be registered.
