Release Notes can't be opened when Firefox is already running.

[Roland Neary]

Binary package hint: ubiquity

If firefox is launched before ubiquity, clicking the 'Release Notes' link gives a 'Firefox is already running but is not responding' error. The release notes are not opened in a new tab of the running firefox instance. When both applications have been restarted the problem does not occur.

The problem occurs in both 1.99.28_amd64 and, after upgrading the live environment, 1.99.31_amd64.

Steps to reproduce:
- boot 9.10beta_amd64 livecd [ and `sudo aptitude install ubiquity` ]
- launch firefox
- click the 'Install Ubuntu 9.10' icon
- click the 'Release Notes' button

This is still an issue on Natty (20110409).

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[LiohMoeller (liohmoeller)]

And of course in Precise - Here it occurs, when you e.g. try to click on the AskUbuntu link if Firefox is already open.

[Stéphane Graber (stgraber)]

The source of the problem is in ubi-language.py in the on_link_clicked function (line 350).

Ubiquity simply uses the gtk url hook to call sensible-browser, my guess is that for some reason sensible-reason doesn't get called as the right user or with the right environment to be able to talk to the running firefox.

This bug was fixed in the package ubiquity - 2.11.33

---------------
ubiquity (2.11.33) quantal; urgency=low

  [ Dmitrijs Ledkovs ]
  * Make Add/Remove/Change toolbar not have a background. Thanks to
    askubuntu and andrewsomething.
  * Fix TypeError in a debug statement when resize is not possible due to
    small total disk space.
  * Remove more of Python 2 support. We are not going back to the __future__.
  * Use py3compile, instead of pycompile.

  [ Stéphane Graber ]
  * Fix drop_all_privileges to also set LOGNAME which is required by firefox
    to contact an existing instance. (LP: #446679)

  [ Colin Watson ]
  * Automatic update of included source packages: debian-installer-utils
    1.91ubuntu4 (LP: #1049535), flash-kernel 3.0~rc.4ubuntu23.
