See the URL for one example. This started happening within the last week. Perhaps r80526 is related? 365594 1 ap 2011-03-10 15:45:52 -0800 Almost certainly related.

When a text node length limit cannot be satisfied due to a composed sequence that's longer than 64K, the result depends on what size data chucks are coming in. 367151 7 85704 ap 2011-03-14 12:54:27 -0700 Created attachment 85704 composed sequence in adjacent nodes I think that it's ultimately a text rendering bug that composed sequences cannot span text nodes.
