            Bug ID: 3552
           Summary: Hang when retrieving IMAP messages behind a captive
                    portal
    Classification: Unclassified
           Product: Claws Mail
           Version: 3.11.1
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Other
          Assignee: users at lists.claws-mail.org
          Reporter: admin at bernsteinforpresident.com

I access the internet primarily through wireless internet with a captive
portal, i.e. when you first connect, all traffic is redirected to the login
page until you authenticate.  Sometimes (but not all the time) claws will hang
upon trying to update my IMAP account.

Steps to reproduce:

1. Connect to the wireless internet (when not yet authenticated)
2. If claws has not already begun an automatic mail check, initiate a manual
mail check.
3. Authenticate in the browser
4. Claws hangs

Note that claws does not hang until a successful connection has been
established.  Before authentication in the portal, claws responds normally.  

A temporary workaround is to just ensure that claws is not in the middle of a
mail check when you authenticate.

I am running Claws 3.11.1 (3.11.1-1ubuntu1ppa1~precise2 package on Ubuntu
12.04).  It is compiled with NetworkManager support (NetworkManager version
0.9.4.0).

Here is the bt:
