Mail keeps crashing

[hkriffraff]

Don't know why, but in the last few days, my Mail client keeps crashing - especially when I click on certain messages in my inbox. Before it was always perfectly stable. Any idea how to troubleshoot this?

Try rebuilding (Mailbox menu) the folders within which these crashing messages are contained. The next step would be to remove a file named com.apple.mail.plist from your Preferences folder whilst Mail is closed.
