No more Precise SRUs in my mind now, so I'd appreciate if you upload it.
Please note that Colin came in and uploaded 0.79.1 but bypassed
Bazaar... Unlike me you know how to best handle that.

@neu: Thanks for being patient. ;-)

Title:
  language-selector should not uninstall packages without a warning
  (allow opt-out)

Status in “language-selector” package in Ubuntu:
  Fix Released
Status in “language-selector” source package in Precise:
  In Progress

Bug description:
  Precise SRU proposal
  ====================

  [Impact]
  When removing a language, not language specific packages are removed as well, some of which you may not want to be deleted. I (gunnarhj) have occationally experienced that e.g. evince and gimp - packages I often use - are suddenly gone. Very annoying!

  [Test Case]
  Steps to reproduce with version 0.79:
  - Install a random language.
  - Launch gnome-language-selector from a terminal window.
  - Start removing the language, but interrupt by clicking "Cancel" when asked to authenticate.
  - Make a note of the list of packages that were about to be removed.

  After installing version 0.79.2 (will be available in precise-proposed):
  - Launch gnome-language-selector from a terminal window.
  - Remove the previously installed language.
  - Note that the list of removed packages is shorter than before.

  [Regression Potential]
  The fix simply restricts which packages are removed. Besides the intentional and harmless effect that some redundant packages are kept when a language is removed, the regression risk is low.

  [Original description]
  After upgrading a recently-installed xubuntu-desktop from breezy to dapper, I ran gnome-language-selector for the first time.

  I selected Norwegian bokmål as my supported (and default) language,
  and pressed apply.   As I watched the debug log, I discovered that
  language-selector removed the xubuntu-desktop, firefox and mozilla-
  mplayer packages _without warning_.

  My language-selector package is version 0.1.15
