Lost connection to MySQL server during query (after 0.8.2 -> 0.8.4)

[olafsep01]

After upgrading to 0.8.4 I get this error frequent. I did a new 0.8.2 install via setup.py and it worked again. Then I did a install of 0.8.3 via setup.py and I got this error.
This error is not exact reproducible. But it occurs after "many" select queries. It look likes it happens with a bigger select query (more data to return).

It is always a select statement (where and order by). The connection to mysql is via tcp-ip (from one virtual machine to another (virtualbox), same hardware).

Probably fix it in repository master branch.
Can you install and test with current master branch ?
