When I try to use the package database, it often does not work, but sometimes it does:
{{{
from fedora.client.pkgdb import PackageDB
pdb = PackageDB()
In [29]: pdb.user_packages("till", acls="owner")["pkgs"]

ServerError Traceback (most recent call last)

= bug analysis =

Maybe there are several backends for the package database and some do not work properly.

Fix the broken component.
