Built a debug version of WebKit, debugged under XCode.  EXC_BAD_ACCESS signal
generated, stack trace below.

in  stack frame #6, the following code is executed:

    m_frontend->setDocument(buildObjectForNode(document, 2,
&m_documentNodeToIdMap));

at that point, document is 0x0, which causes the eventual signal.  

Implies that also at stack frame #6, the call to mainFrameDocument() returns
0x0.

At this point, I'm lost, assume pfeldman will have a handle on this, not
investigating any further.
