bzr builddep doesn't work after modifying files

[Li The G No Lie]

Hello,

I was following the guide wanting to fix a bug in plasmate (https://bugs.launchpad.net/ubuntu/+source/plasmate/+bug/1464910). Checking out and branching the code worked fine ( bzr branch ubuntu:plasmate), but as soon as I made a change I would get:

dpkg-source: info: local changes detected, the modified files are:
 plasmate-1.0/plasmate/CMakeLists.txt
dpkg-source: error: aborting due to unexpected upstream changes, see /tmp/plasmate_1.0-0ubuntu4.diff.Rj0MXp
dpkg-source: info: you can integrate the local changes with dpkg-source --commit

Well, I ran `dpkg-source --commit` and got

dpkg-source: error: no upstream tarball found at ../plasmate_1.0.orig.tar.{bz2,gz,lzma,xz}

I am at wits end after searching everywhere for an answer. I think the guide has to be updated to include this scenario and a solution to it. I can't be the only one running into it.
