I have an open-source application on the Android market. It seems to work fine for me (with over 1,000 active installs, I have to presume that it works for most people).
The bug turns out to be an undocumented default on (some?) Samsung phones that limits the maxLength attribute of a TextView widget to 9,000 characters. Explicitly adding an "android:maxLength" attribute with a value large enough to contain my largest text length to the TextView widget solved the problem.
Incidentally, I believe that this same issue is what caused the LogCollector logs from the initial reporters to be truncated.
