I noticed the same bug using the commandline interface, tags are not displayed correctly.
$ aptitude show autoconf
Package: autoconf
[...]
Tag: code-generator, devel::{buildtools, interface::commandline, lang:c},
role::program, scope::utility
$
The problem seems to be caused by incorrect parsing of grouped tags; autoconf,
for example, has the following tags in the Package file:
Tag: devel::{buildtools,code-generator,lang:c}, interface::commandline,
role::program, scope::utility
The tags belonging to the devel:: facet are grouped together using curly
braces, and it's very likely that this is what makes aptitude screw up.
