aptitude segfault on UML

[Randall Smith <randall@tnr.cc>]

I installed a UML Etch dist as described here:

http://www.punknix.com/?q=virtualization_uml

aptitude segfaults on everything I've tried except update.  Here is 
example output.

ws-uml:~# aptitude install python
Reading package lists... Done
Building dependency tree... Done
Initializing package states... Done
Reading task descriptions... Done
Building tag database... Done
Segmentation fault

Any idea what might cause aptitude to segfault.  BTW, apt-get works fine.
