[Nix-dev] bug? nix-env -qa doesnt find what it should

[Axel Grosz]

$ nix-env -qa tomcat
error: selector `tomcat' matches no derivations
$ nix-env -qa 'tomcat*'
error: selector `tomcat*' matches no derivations
$ nix-env -qa '*' | grep tomcat
apache-tomcat-6.0.18
jakarta-tomcat-5.0.27
tomcat-connectors-1.2.26
tomcat-mysql-jdbc

thats on nix-0.13pre15214 on an ubuntu 8.10
the nix-0.12 did work correctly if i remember right
my system:
<item attrPath="nixpkgs_stable.nixUnstable" installed="1" 
name="nix-0.13pre15214" substitutable="1" system="x86_64-linux" valid="1">
