What's the actual full assertion text?  And the top 5-6 stack frames?

Hmm.  So aFrame is a text frame for two newlines, but mWordFrames->PeekFront()
is the zero-length text that content: inserts here.  roc, dbaron, any idea
what's going on?

WFM on Mac trunk.  I guess I should test Windows too, since I reported it on Windows.
