This bug was detected on Chromium:
http://code.google.com/p/chromium/issues/detail?id=17023

The chromium crash reporting tool identified a few different crash stacks that
fail on the same method. Here is one such stack trace:

0x6bc0fc59 [chrome.dll- node.cpp:781]WebCore::Node::nodeIndex()
0x6bc00f1e [chrome.dll- rangeboundarypoint.h:100]
WebCore::RangeBoundaryPoint::offset()
0x6bc0360f [chrome.dll- range.cpp:1762] WebCore::boundaryTextNodesMerged
0x6bbe863e [chrome.dll- document.cpp:2718]
WebCore::Document::textNodesMerged(WebCore::Text *,unsigned int)            
0x6bc0f9d2 [chrome.dll - node.cpp:622] WebCore::Node::normalize()
0x6bc838cf [chrome.dll- v8node.cpp:236]
WebCore::NodeInternal::normalizeCallback
0x6c25d0a5 [chrome.dll- builtins.cc:381] v8::internal::Builtin_HandleApiCall
0x6c25a1cf [chrome.dll + 0x006ba1cf] 
0x030e6d9c

I haven't been able to reproduce this crash, but I suspect this had to do with
simultaneous Range Selection and Node editing.
