Depends on the repository. Also on Windows, I see the following sizes for featureless (duplicate) tiles from the various standard Maemo Mapper map sources:

Google Streets: 103 bytes
Virtual Earth Streets: 106 bytes
Virtual Earth Satellite or Hybrid: 1652 bytes

Among my Google Satellite downloads, I have a lot of duplicate 1755 byte files, which in fact are NOT maps, even though they commonly appear clustered in featureless ocean areas. (Some of the true satellite map files are actually smaller.) Opening these files as text reveals the following HTML error page, saved under the target JPG filename:
