Thank you for the bug report! It looks like that it is not enough to Require: dnf, we have to Require: python3-dnf.

Can you please install python3-dnf, re-test and report the results here?

I found that the exception is raised when I tell abrt to generate the stacktrace locally (instead of uploading it).

python3-dnf is already installed:

[root@saturn giulio]# dnf install python3-dnf
Fedora 23 - x86_64 - Updates                    110  B/s | 257  B     00:02    
Last metadata expiration check performed 0:00:00 ago on Wed Jul 22 22:28:51 2015.
Package python3-dnf-1.0.1-3.fc23.noarch is already installed, skipping.
Dependencies resolved.
Nothing to do.
Complete!

Hmm, python3-dnf is installed and the uncaught exception is reproducible.
Can you please provide the output of the following commands?

$ echo "import sys; import dnf; print(dir(dnf))" | python3
$ rpm -V python3-dnf
$ ls -arl /usr/lib/python3.4/site-packages/dnf/

The second one returns no output.

[giulio@saturn ~]$ echo "import sys; import dnf; print(dir(dnf))" | python3

This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '23'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
