Comment 1 Michael Schwendt 2012-05-23 21:14:07 UTC
Bodhi refuses to add the bug IDs with the initial submission and continues to refuse doing that:

| 500 Internal error
| 
| The server encountered an unexpected condition which prevented it from
| fulfilling the request.

Tried half a dozen times to edit the ticket. Always error 500:
https://admin.fedoraproject.org/updates/python-feedparser-5.1.2-2.fc17

[...]

Dunno about Fedora 15 and 16, which are stuck at feedparser 5.0.1. Package owner has had objections to update to 5.1 
  https://bugzilla.redhat.com/show_bug.cgi?id=787401#c1
and has not responded to the request to update to 5.1.2 (the security fix) since May 8th: https://bugzilla.redhat.com/show_bug.cgi?id=787401#c12

Comment 2 Vincent Danen 2012-05-23 22:41:44 UTC
I suspect an issue with the recent bugzilla is causing that error you're seeing from bodhi (unfortunately).  Just tried and no error, but no access either.

I'm not so concerned about Fedora 15, but it would be good to get this into Fedora 16.  I'll add a comment to the noted bug.  Thanks.

Comment 3 Fedora Update System 2012-05-24 07:37:59 UTC
python-feedparser-5.1.2-2.fc17 has been submitted as an update for Fedora 17.
https://admin.fedoraproject.org/updates/python-feedparser-5.1.2-2.fc17

Comment 4 Fedora Update System 2012-06-01 17:15:04 UTC
python-feedparser-5.1.2-2.fc17 has been pushed to the Fedora 17 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 5 Fedora End Of Life 2013-01-17 02:00:12 UTC
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. 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bug reports from releases that are no longer maintained.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 WONTFIX if it remains open with a Fedora 
'version' of '16'.

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 prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 16 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 to click on 
"Clone This Bug" and open it against that version of Fedora.

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.

The process we are following is described here:
