I've imported bulgaria.osm into a Nominatim VM, and reverse.php with zoom=18 & addressdetails=1 returns a blank page for coordinates in Bulgaria (it works fine on other imports of other countries).
After tracing it, I found the problem:
inside the Nominatim "functions.sql", there is a type called "addressline". This type has a field called osm_id. This field is defined as INTEGER, but there are locations in Bulgaria (and I'm guessing elsewhere) that the OSM_ID is higher then the maximum INTEGER number.. I changed it to BIGINT, recreated the type and the get_addressdata function which depends on it, and everything is OK.
I can see the problem in
