This problem with the CPs crashing can occur at the time of a dialog login because the user name contains a backslash character (\). The use of a backslash is not allowed in a user name.



This issue can be avoided by not allowing backslashes as part of user names.  This will be resolved in the SP5 HF1 release for AE v9.
