Steps to reproduce:
I don't know wether this is the root cause of all of the crash on send bugs
which are open but I can reproduce this 100% of the time.

What you need to reproduce:
1. a domain with hostname wildcards (where *.domainname.com all point to the
same IP)

Background:
I have been using IMAP mail on my own domain "jasonclinton.com"; I recently
moved the IMAP server to "mail.jasonclinton.com". This caused the 'crash on
send' bug to start.

Steps to reproduce:
1. add a new IMAP account account
2. sent the "Sent Mail Folder" to something on the IMAP server
3. in the IMAP account properties, change the hostname of the IMAP server

The crash is occuring because the camel provider URI's for the Sent mail folder
are still pointing to the old domain name. In my case, they were pointing to
"jasonclinton.com" instead of the new "mail.jasonclinton.com".

Steps to stop crashing and get a meaningful error message:
1. delete the .evolution/mail/imap/username@OLDdomain.com folder

Steps to resolve entirely:
1. manually reconfigure the Sent mail folder so that the internally stored URI
points to the new domain name

Stack trace:
No stack trace.

Other information:
Hope this helps the several people who have open bug reports on send mail crashing.
