This comes from dbconfig-common, not directly from sympa itself.

The problem happens if there is no database configured when the prerm 
script is invoked. I was able to trigger this on another package by 
installing without a database (question dbconfig-install=false), and 
then running dpkg-reconfigure on the package.

Patched attached to add the missing quotes.

Thanks

Chris
