Hello

I don't see any problem, your config works for me (without the obvious
typo of missing semicolon in filter export_OSPF), default route is exported
in both 1.3.9 and 1.3.6 (default route could be seen in both 'show ospf state'
and 'show ospf lsadb').

There were some bugs in pre-1.3.9 that causes default route to disappear
or does not allow to export routes to OSPF, but they were all related
to configurations with multiple areas.

Your config would not work if there is already one default route in OSPF domain,
it would be imported to main routing table and blocks exporting the default
route from kernel protocol (because of higher default priority of OSPF routes),
but this you could see in 'show route'.

You could try to change export in OSPF to 'export all', try to replace
kernel default route with static default route, or you could change area
in OSPF to 0.0.0.0 (backbone) to see what your problem is related to.
