Notes for patching Thunar on Ubuntu

Install build and packaging tools
  $ sudo apt-get install packaging-dev ubuntu-keyring devscripts equivs

Make build directory
  $ mkdir ~/thunar-build
  $ cd ~/thunar-build

Download the thunar .dsc file and extract source and config tarballs
  $ dget -x http://archive.ubuntu.com/ubuntu/pool/universe/t/thunar/thunar_1.6.10-2ubuntu1.dsc

NOTE: dget will download the original source tarball and debian config from
  http://archive.ubuntu.com/ubuntu/pool/universe/t/thunar/thunar_1.6.10.orig.tar.bz2
  http://archive.ubuntu.com/ubuntu/pool/universe/t/thunar/thunar_1.6.10-2ubuntu1.debian.tar.xz
and extract the tarballs into ./Thunar-1.6.10.

If dget fails to download or extract the files, then download the tarballs,
extract the file thunar_1.6.10.orig.tar.bz2 into ~/thunar-build,
and extract thunar_1.6.10-2ubuntu1.debian.tar.xz into ./Thunar-1.6.10.

Install build dependencies as found in debian/control
  $ cd Thunar-1.6.10
  $ sudo mk-build-deps -i -r

Set an inferior version label and update changelog
  $ dch --local ~patch "Fix file rename and move crashes"

Download patch file into debian/patches directory
  $ wget -O debian/patches/rename.patch http://bug-attachment.xfce.org/attachment.cgi?id=6779
  
Validate the contents of the rename.patch file.
  $ less debian/patches/rename.patch

Modify the debian/patches/series file
  $ vi debian/patches/series

Delete conflicting patch from debian/patches/series file
  02_Fix-crashes-when-reloading-target-file-after-move.patch

Insert new patch into debian/patches/series file
  rename.patch

Validate the contents of the series file.
  $ less debian/patches/series

Build the packages without GPG signing
  $ dpkg-buildpackage -us -uc

Install the new packages
  $ sudo dpkg -i ../thunar-data_1.6.10-2ubuntu1~patch1_all.deb
  $ sudo dpkg -i ../libthunarx-2-0_1.6.10-2ubuntu1~patch1_amd64.deb
  $ sudo dpkg -i ../thunar_1.6.10-2ubuntu1~patch1_amd64.deb

NOTE: These packages will be replaced by the current version in the repo on next apt-get upgrade due to setting an inferior version label ~patch.

Remove the thunar-build-deps package
  $ sudo apt-get remove thunar-build-deps
  
Delete the build directory
  $ cd
  $ rm -rf ~/thunar-build

Reboot and enjoy!
