fix for the problem

Sent upstream. Hopefully included soon.

Comment 2 Rik van Riel 2007-03-27 16:01:31 UTC
Glauber, did your fix get accepted upstream?

Is it in our RHEL and Fedora packages?

Comment 3 Glauber Costa 2007-03-28 16:13:52 UTC
Yes rik, this was accepted upstream, although with some little changes. It is in
our RHEL tree. As it went upstream sometime ago, it might have made into fedora
through the rebases.

Comment 4 Red Hat Bugzilla 2007-07-25 01:36:09 UTC

Comment 5 Chris Lalancette 2008-02-26 23:43:32 UTC
This report targets FC6, which is now end-of-life.

Please re-test against Fedora 7 or later, and if the issue persists, open a new bug.
