This is a known problem with debug ROMs, where any alert which winds
up with one or more linefeeds at the end of the text message will
trigger an invalid insertion point warning from the field code.

Actually the problem is that the alert code intentionally reduces the
height of the text field bounding rectangle so that the trailing
linefeeds are truncated. Unfortunately the insertion point was set to
the end of the text when the field was created, and the insertion
point visible flag was also set true, so the field code correctly
complains about a situation where the insertion point should be
visible but it isn't.
The only work-around currently is the one you suggest, which is to
strip off trailing linefeeds yourself.
