This bug was reported automaticaly in connection with IPv6 project. Our aim is to support IPv6 in all Fedora Core packages so FC6 and RHEL5 will be ready for IPv6. This package seems to lack IPv6 support as is illustrated in attached log. Here follows part of scanning log (grep -r F_INET *)/up to 30 lines: /libXmu-1.0.2/src/CvtStdSel.c:236: if (hostp->h_addrtype != AF_INET) return False;
Please report this issue to X.Org developers by filing a bug report in the X.Org bugzilla located at http://bugs.freedesktop.org in the "xorg" component. Once you've filed your bug report to X.Org, if you paste the new bug URL here, Red Hat will continue to track the issue in the centralized X.Org bug tracker, and will review any bug fixes that become available for consideration in future updates. Setting status to "NEEDINFO_REPORTER", awaiting X.Org bug URL for tracking.
It appears that libXmu doesn't support IPv6 at all and needs to be updated to handle the IPv6 case or be more agnosticly written. We disable TCP/IP support in X by default and strongly recommend that people use ssh with X11 forwarding instead of using X protocol over TCP/IP directly. When used in this manner, IPv6 support is provided by ssh itself, which covers the majority of our userbase. I have filed a bug in X.Org bugzilla to track support for IPv6 in libXmu, and once upstream has implemented this, we will include it in future OS releases: https://bugs.freedesktop.org/show_bug.cgi?id=7611 Setting status to UPSTREAM
