Smart group causes Mail to crash

Question

I created a smart group that immediately caused Mail (3.6 (936)) to crash (apparently).
Since, I have been unable to launch Mail normally - it starts with the smart group in question selected, and then crashes, I need to force quit it.
I have tried to launch Mail with shift pressed down. It starts, and works, up to the moment I select this smart group. I can modify it, and perform delete command, but this is never executed, Mail crashes... Any suggestions?

hmibrooklyn I tried and failed to get Mail to crash by following what you described. Until someone else has anything more constructive to add I suggest the following, in no particular order. Try each suggestion and determine if any one of them keeps Mail from crashing.
Try copying the text from Pages, but instead of pasting it select Paste and Match Style from Mail's Edit menu before formatting it as a numbered list.
Before composing the message select Make Plain Text from Mail's Format menu.
If you have more than one Mail account, perform the same action using a different Mail account.
Open Font Book - it's in your Applications folder. Select All Fonts from the Collections column, then select any of the fonts in the adjoining column, then Select All from the Edit menu. Then, select Validate Fonts from the File menu.
The end result ought to resemble the following screenshot. If it does not, report any errors it encounters.
Create a new, temporary User account to determine if the problem exists while using it instead of your usual one: Isolating an issue by using another user account
You will have to configure a Mail account for the temporary User account, but you can use the settings from the existing Mail account.
Delete the temporary User account when you are finished with it.
That's all I can think of for now.
