5.0 minilogin unable to connect to world server

[Drawde]

I have the latest 0.50 CVS, the 0.5.0+ minilogin.exe and the latest db.sql downloaded from the CVS site.
However the world server seems to be unable to connect to the login server. The world server gives this
error :

Login server responded with FatalError. Disabling reconnect.
Error message: 'Bad server name. Unknown reason.'
127.0.0.1:5999: TCPConnection::RecvData(): Error: 10054

and the minilogin server gives this error:

Server failed name check: 127.0.0.1:1875

The server name I normally use is "eqemu" but I have tried changing it to other names, which gives the same
error.

This is the data in loginserver.ini:
[LoginServer]
loginserver=localhost
loginport=5999
worldname=eqemu
worldaddress=localhost
locked=false

Strangely, the old 0.44 minilogin connected OK, but it gave an "incorrect version" message in the EQ client.
