If I load the following HTML into composer: <html><body><i>Line 1<br>Line 2 <b>bold text</b></i></body></html> and follow these steps, I crash: 1. Load sample file in composer. 2. Click after "bold text" to place the caret at the end of the line. 3. Hit the return key. 4. Type a word. (Notice that what you typed is bold) 5. Select the word you typed. 6. Hit the bold button on the tool bar to unbold the selection. 7. Ctrl-Z to undo. (Notice that what you typed and "bold text" disappear?) 8. Ctrl-Z to undo again. You should now crash!

nsBranch -- need to get a fix in the trunk as quick as possible

I just attatched a JS test case that reproduces the crash without an Editor!
Just press the buttons in the test case to reproduce the crash. Use the "Dump
Contents" button, at any point before you crash, to see what the current dom
tree looks like.
Step 1 is basically changing this:
<i><b>bold text<br></b>more text<b><br></b></i>
to this:
<i><b>bold text<br>more text<br></b></i>
You'll notice that after Step 1, new frames are not created for the portion of
the doc that changed, so it looks like the content disappears. But it's actually
there in the DOM tree.
If you then try to modify any portion of the dom tree we modified in step 1, you
will crash! (Step 2)Assignee: kin → attinasi

waterson said he'd like to take a look at this one. I'm thinking bug 90528 might also be caused by whatever is causing this bug.

This is caused by the same basic problem that is causing bug 84645. We need to fix up |parentFrame| in ContentInserted() if we're inserting beneath a continuation. *** This bug has been marked as a duplicate of 84645 ***
