Comment (by tchx84):

 This bug is still present in Ubuntu 14.04 LTS (Trusty) and affects web
 activities such as Gears [1], FindWords [2] and possibly all others.

 As it was described in a previous ticket [3] for Wikipedia activity, the
 bug can be reproduced with Manuq's libsoup test case [4] by running the
 script when no active network is set.

 Steps:
 1. Install our Ubuntu image with 0.105.2.
 2. Connect to an access point (AP).
 3. Go to the terminal activity and run libsoup test case [4], and it
 should pass, stating that it resolves "localhost" but it can't connect (of
 course it won't there is no real server to connect to)
 4. Now, disconnect from the AP and repeat step 3. The error will be that
 is not possible to resolve "localhost".

 Another way to reproduce is to replace step 3 by opening web activities.
 When there is no active network, the activities won't be able to connect
 to the sugar websocket and will not load user colors, previous data and it
 won't be closed by clicking on the close button.

 As stated for Wikipedia activity case, there are only 2 workaround:
 A) Modify all web activities to use 0.0.0.0 instead of localhost, or
 B) Insert a "::1 localhost" entry in /etc/hosts
