I could be misremembering, but I think bzr-buildpackage (UDD?) will unapply the patches before it tries to merge in a new version. It's very handy to have the patch-applied branch to work on directly for daily packaging tasks, but I do think when merging branches you have to do that on the *unpatched* tree. Cheers, -Barry
