Comment 13 for bug 339131

Qt 4.5.1 does break the version of Amarok shipped with Kubuntu by default; the center pane starts to throw a fit. (fixed in 2.1, but we can't SRU that either.), So while we'd love to SRU this (it fixes quite a few bugs), it just isn't possible given the regressions involved and the amount of apps at risk for potential regression. It will probably be possible to eventually backport 4.5.1 given enough testing, though.
