This bug is semi-reproducible, although after following the steps below this
particular behavior probably only happens 1 in 10 times.  It relies on the
behavior from Bug 10143, which may be suspect in the first place.  This bug may
become unreproducible if Bug 10143 is fixed.

Steps to reproduce:

1. Follow steps from Bug 10143 Comment #0:
    a. Open Bug 8278.
    b. Click "[reply]" link on Bug 8278 Comment #5.
    c. Put cursor on "blank" line between two paragraphs.
    d. Hit Delete key twice.
2. Use the mouse to place the cursor to the left of the greater-than character
(">") on last line with a greater-than character (">").
3. Holding the Shift key down, arrow down twice.  This should highlight the
entire last two lines in the textarea.
4. Hit the Delete key.
5. Use the mouse to place the cursor on the first of two blank lines (the top
blank line) between the quoted paragraphs.
6. Hit Enter.

Expected results:

A blank line is added between the two quoted paragraphs.

Actual results:

One of the following:

- A blank line is inserted with no crash or hang (expected resutls!).
- A hang occurs (this bug).
- A crash occurs (Bug 10141 or a different crash).

Note that if the expect results occur, do the following:

A. Select all text in the textarea.
B. Hit Delete.
C. Start from Step 1b above.
Regression:

This does not occur on production Safari 2.0.4 (419.3) on Mac OS X 10.4.7
(8J135/PowerPC).
