Description Rich Coe 2006-08-14 14:20:32 UTC 
This is a follow up to bug 6956.

When shutting down apps in an appgroup, its possible to crash the Xserver.
I don't know if this is dependent on a busy host or not.

A for-loop in CheckConnections() uses a local copy of the select file descriptor
list, which can change when an appgroup is shutting down.

The attached patch checks for a valid ConnectionTranslation entry prior
to calling CloseDownClient() with a null value.
