Time Zone selector hangs and ubiquity freezes if network connection is firewalled

[Jean-Baptiste Lallement]

TEST CASE:
1. Use a system connected to the network but which doesn't have access to Internet
2. Proceed to step 'Where are you'
3. In the time zone field, enter 'New'

Result:
the UI freezes and ubiquity must be killed.

I can confirm this happened with A3 as well. I have been able to reproduce with QEMU in both ISOs.

This bug is impacting OEM installations and previous methods to work around this no longer work.

[Steve Langasek (vorlon)]

Tentatively claiming for final release... guys, does this look feasible?

[Colin Watson (cjwatson)]

Yeah, we're opening the URL directly in a GTK+ signal handler; that needs to be a proper callback instead.

[Colin Watson (cjwatson)]

My vote is for using libsoup to fix this, I think, since it supports asynchronous I/O (which urllib2 doesn't) and also supports direct control of HTTP headers (which GIO doesn't), as well as having gobject-introspection bindings.

This bug was fixed in the package ubiquity - 2.8.0

---------------
ubiquity (2.8.0) oneiric; urgency=low

  * Fix SSID UTF-8 decoding, and replace any still-invalid characters with
    the Unicode replacement character just in case (LP: #839143).
  * GTK frontend:
    - Fetch geoname data asynchronously (LP: #837217).
  * Always start oem-config with LANG=en_US.UTF-8; this doesn't affect
    translations since we use debconf for those, but forces Qt to use UTF-8
    encoding for text fields (LP: #837042).
