Can't access DTP 2.2.1 via WebInterface in Safari

When I launch DTP’s web server and try to access it using Safari, I just see the short Devon Loading indicator and then I’m led to an empty page; dto. in Google Chrome (latest). Firefox 4 works, so it seems to have something to do with WebKit.

Mostly 2 errors show up:

The first error doesn’t appear always. It seems to be a subsequent error from something else?!
GET andyimac.local:8081/desktop/Fram … undation.j 404 (Not Found)

This error shows up in Safari all the time:
TypeError: ‘null’ is not an object (evaluating ‘“absolute”’)

I resetted Safari already, but to no avail.

Any idea?

iMac 27" 2,93 GHz Intel Core i7, 12GB RAM
MacOS X 10.7.1 (11B26)
Safari Version 5.1 (7534.48.3)

This is unfortunately an issue of WebKit-based browsers on Lion. Until a future 10.7.x release will fix this, it’s recommended to use e.g. Firefox.

na toll… und wenn man dann den Firefox hernimmt, heisst es, dass dies ein PDF sei und man sollte gefälligst Safari hernehmen… leider ein wenig enttäuschend.

Any news on that one? I’d really like to use DTP for my wife’s office, but without pdf preview either within firefox or an usable safari I cannot do that.
