[Greasemonkey] Cannot install scripts (FF 1.5b2, GM 0.6.3)

[niels at myplace.dk]

I use Firefox 1.5 Beta 2 and greasemonkey 0.6.3 (from the mailing list). When I
try to install any userscript I get this javascript alert:


Error installing user script:

[Exception... "Component returned failure code: 0x80520012
(NS_ERROR_FILE_NOT_FOUND)
[nsIChannel.open]" nsresult: "0x80520012 (NS_ERROR_FILE_NOT_FOUND)" location:
"JS frame ::
chrome://greasemonkey/content/utils.js :: getContents :: line 165" data: no]


I get nothing at the javascript console.
