Update to 17.0

This bug was fixed in the package thunderbird - 17.0+build2-0ubuntu0.12.04.1

---------------
thunderbird (17.0+build2-0ubuntu0.12.04.1) precise-security; urgency=low

  * New upstream stable release (THUNDERBIRD_17_0_BUILD2)
    - see LP: #1080212 for USN information

  * Update globalmenu-extension to 3.6.4
    - Fix a build ordering issue causing the install.rdf to be missed
      from the addon xpi
    - Fix crash in uGlobalMenu::InitializePopup
    - Make logging work correctly on debug builds
    - Handle submenu's being reopened without getting a close event
      in between. We don't seem to get a close event when a menuitem
      is activated
  * Update messagingmenu extenstion to 1.3.1
    - Use the nativeHandle attribute on Thunderbird versions that support
      this, and avoid creating a window just to set the event timestamp
    - Ignore case when comparing email addresses (thanks Tom Jaeger)
    - Stop using nsIMsgMessageService.streamHeaders, as this doesn't work
      reliably all of the time (and has been triggering a crash too)
    - Properly disconnect from gobject signals. Even though our signal
      handlers are implicitly disconnected when we drop the last reference
      to objects that we own, we actually leak the ctypes function object
      if we don't explicitly disconnect, due to the way that they are
      implemented
  * Build with --disable-webrtc on all architectures except for i386 and amd64
    - update debian/config/mozconfig.in
  * Update eds extension to 0.5
    - Lots of refactoring
    - Make contact list commit async
    - Fix LP: #919612 - cannot write contact, with "Could not save nsIAbEDSCard
      property: SecondEmail" errors in the error console
    - Make setting dates work as expected
    - When selecting a generic image, clear the actual image property rather
      than saving the generic image pixel data to EDS
    - Ensure that phone numbers are displayed in the preview pane for EDS
      contacts
    - Use the upstream chat tab for managing IM handles. This requires
      Thunderbird 15
    - Ensure that chat handles appear in the contact preview pane
    - Make the preferred mail format option work (was always disabled in
      the edit UI)
    - Support storing Google Talk ID's in eds
    - Implement nsAbEDSCard.deleteProperty
    - For number fields, handle the case where the passed in value converts
      to NaN
    - Implement nsAbEDSCard.copy and make nsAbEDSDirectory.addCard use this
    - Ensure we dispatch a notification when a directory name changes
    - Implement nsAbEDSDirectory.modifyCard and hide nsAbEDSCard.commit
    - Make contact list creation work properly
    - Display the year field in the contact editor for the anniversary date.
      This is supported fine by eds
    - Make copying contacts between EDS and non-EDS addressbooks work more
      reliably, rather than dropping fields such as PrimaryEmail
    - When copying a Thunderbird contact to an EDS folder, add the Thunderbird
      custom fields as "X-THUNDERBIRD-CUSTOM-*" vcard properties, rather than
      adding them to the note field
    - Don't unload libraries on shutdown. May fix a common shutdown crash
