[jQuery] firefox2 parsererror in jquery .ajax but not in browser

[jQuery] firefox2 parsererror in jquery .ajax but not in browser


I'm trying to access an xml document via .ajax but it goes to the
error handler... I get no properties in the errorThrown object, and
the only clue I have is "textStatus" which tells me "parsererror"
only.
more clues:
- if i directly access the xml document/request firefox can parse it
fine and displays the raw xml
- firebug shows headers and response document
- content type correctly set
- ie7/ff3 works fine
Thanks in advance!
