David and I have arrived at a somewhat more appealing fix:

1. In kickerrc (usually in /home/<user>/.kde/share/config), add 
the following under [General]:

    SecurityLevel = 0

This forces kicker to consider all applets as "untrustworthy" - 
it still loads them, but is uses 'appletproxy' to load them. 
That creates a separate process for each applet.

This basically does the same thing David suggested originally, 
but without hacking kicker.

2. If you want some applets (but not currently more than one 
Python based applet) to load internally to kicker, add:

    TrustedApplets =

Sorry, but I don't know the format. I would imagine it's a 
comma-delimited list of applet names, but I couldn't find any 
docs on what those might be.

I still think there's a better fix possible - probably involving 
modifications to the Python interpreter wrapper I added to 
PyKDE. I'll be looking into it over the next several weeks.
