Delete card loop crashes Rev

[Frank D. Engel, Jr.]

Also, as pointed out previously on this list, anything which causes Rev 
to crash is and should be treated as a bug (the only possible exception 
would be a custom external which causes the crash, but you would likely 
know if you were using one, and none of the code you posted would seem 
to indicate the use of an external).  This should be filed in Bugzilla, 
prefereably with a crash log, which can be obtained from the Console 
application in the Applications/Utilities folder under OS X.
