In my case the cause is what looks like a bug in mod_perl2. The object handling request parameters (Apache2::Request) failed to initialise where expected. I have not been able to create a proper test case for it as it needs a quite specific scenario. If anyone is interested I can email then more details, anything posted on here would be out of context.
Thanks for your time and help.
