Crash in mail compose editor. 5/25 pm build of M6 candidate. I was editing in the mail compose window (HTML) and using the backspace key when I crashed. I don't have the exact steps though. I'm hoping this talkback report will help you. Talkback incident ID 9062020.

unable to reproduce so far. can anyone in qa land get this to happen again?

I'll try again. Does the stack trace give you any clues?

I can't reproduce this immediately. I'm going to leave this bug "verified" for a few days while I try to use the mail compose window some more over the next few days.

the stack trace is useful but hasn't shed enough light for me to know what is going on. I haven't been able to find a problem with GetBlockNodeParent(). Note that this code has moved, so if you get the crash again, you may see it in nsEditor::GetBlockNodeParent() instead of nsHTMLEditRules::GetBlockNodeParent().

I have not seen this after recent usage. As I use the mail compose window more and I see this bug again, I will reopen or open a new bug.
