Well, first saw this in test11-pre1, and now in test11-pre4 I report it again.

From: Jorge Nerin <[email protected]>

Well, first saw this in test11-pre1, and now in test11-pre4 I report it again.

Do you use any one of USB, PCMCIA+Yenta, or ATM? If so, please give the following patch a try.

If not, do you use KHTTPD? If so, please don't... it's unmaintained, buggy, and to eventually be replaced by TUX.
