IIRC the "option=XX" parser has not yet been fixed to handled byte sizes
like that. The above means "minimum 4 bytes".

Your earlier "min-size=4194304" should have worked.

Run "more 00000000" on the small file and see what URL its saved from
and what the HTTP headers were.

It could be a few things:
  * one of a few internal files (netdb amd clientdb) which require
saving to disk somewhere and pick the first cache_dir.

  * a large file still arriving from the network.

  * unknown-length files which are assumed to have an extremely big size
until they have arrived. Which has not yet been erased.

Also, please try an upgrade to the backports.org version in case this is
a fixed bug already.
