We know that the cause of this is deep in the XML frameworks in

passage of xml in one of our doc set feeds, but haven't been able
to isolate exactly which one. Safari 4 seems innocent in this; it
was happening well before Safari 4 Beta availability.
I hit this multiple times per day and had been chalking it up to
Safari 4. If there is some bit of data I can send in to help find
the problem, I'd be happy to do that...
What's weird about this is that if you run Xcode under gdb with a
breakpoint set on __xmlRaiseError, you will ALWAYS hit the breakpoint
when you first switch to one of the newer iPhone docsets.
Hitting this breakpoint doesn't guarantee a crash, but it seems to be
somewhat predictive.
Stack trace looks like this:
#0 0x93f8debb in __xmlRaiseError ()
#1 0x93f73ee3 in xmlParseChunk ()
#2 0x9575a5c9 in WebCore::XMLTokenizer::doWrite ()
