            Bug ID: 304281
          Severity: crash
           Version: 1.3.1
          Priority: NOR
          Assignee: konversation-devel at kde.org
           Summary: Konversation crash with LDAP auth over SSH tunnel
    Classification: Unclassified
                OS: Linux
          Reporter: eljefedelito at gmail.com
          Hardware: Debian stable
            Status: UNCONFIRMED
         Component: general
           Product: konversation

Application: konversation (1.3.1)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 3.2.0-2-686-pae i686
Distribution: Debian GNU/Linux 6.0.5 (squeeze)

-- Information about the crash:
I created an SSH tunnel through my employer's gateway server:
ssh -X -t -t -t -l username -L 6697:irc.employer.com:6697  gateway.employer.com

and the SSH worked fine but LDAP Auth failed me.  I changed the Konversation
Identity to one that my employer would know (my work's username) and when
trying to connect, Konversation crashed.  Every time.

The crash can be reproduced every time.

 -- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
