Comment 1 Matt Domsch 2010-11-28 14:13:04 UTC

If Fedora has no specific patches in this area,  can file it with upstream bugzilla.

Comment 2 Matt Domsch 2010-11-28 19:42:39 UTC

Filed upstream.

Comment 3 Kyle McMartin 2010-12-09 23:20:24 UTC

Thanks Matt. Please let us know when/if there is a fix to merge.

Comment 4 Kyle McMartin 2010-12-09 23:40:04 UTC

Ah, it already has been. Looks annoying enough that I committed to F-14. Will be in the next build.

regards, Kyle

Comment 5 Kyle McMartin 2010-12-10 00:03:20 UTC

Ok, copied the fix to F14/rawhide too.

Comment 6 John W. Linville 2011-01-13 19:16:53 UTC

Closing on bases of comment 4 and comment 5...
