Comment 1 Josh Boyer 2012-05-23 16:03:39 UTC 
FYI.  This was fixed in 3.3.5 (stable commit 4a265435c87b19175c3906ff49ffe5bf4a4cc228).  All Fedora branches are on that or newer already.
Comment 2 Josh Boyer 2012-05-23 16:04:15 UTC 
Sorry, that should have been stable commit 9f4660213e58b3b78dc75bf3e3b4126dbe9a0b14
