kontact/kmail becomes unresponsive when reading a new message in a filtered

This continues on - the trace I have repeats the unreadMail line another 1500+
times, and I suspect the only reason it doesn't go back more is because I quit
looking.  There is apparently some sort of infinite loop happening here.

Reproducible: Didn't try

Steps to Reproduce:
Read some unread mail by moving to a new folder.  Not sure what else it takes.


Expected Results:  
Able to copy&paste from an email that wasn't read prior to this (i.e., no hang)
