W2600: Exception occured: Accessviolation at address 0040AA7A in module 'HTTPService.exe'

I have a form with an input array field. When I submit the form I get the error mentioned above in the HTTP Server log. I already set my server input to accept PHP Arrays. Can anyone help with this?

I would guess that the field names in your form are not XML compliant, i.e. they contain spaces or brackets.
