            Bug ID: 309954
          Severity: crash
           Version: 2.9.3
          Priority: NOR
          Assignee: konsole-devel at kde.org
           Summary: Unexpected konsole crash
    Classification: Unclassified
                OS: Linux
          Reporter: nick at leverton.org
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: konsole

Application: konsole (2.9.3)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-18-generic i686
Distribution: Ubuntu 12.10

-- Information about the crash:
I had just rebooted after upgrading from 4.9.3 to 4.9.4.  I have a manually
saved KDE session which is set to restore at boot.  It includes two konsole
sessions each with multiple tabs.

Konsole had loaded but konqui was still reloading its pre-shutdown windows
(from the automatic state save, they are not part of the saved session).  as i
was in a hurry I started using konsole.

I typed in a password for ssh-agent and then started an apt-get update for
anything that had been further changed over the weekend.  konsole crashed
whilst this was in progress (note update, not upgrade, so no binaries should
have been replaced).

this is the only konsole crash i can recall since starting on kde 2.2 so it's
slightly worrying that a simple isspace() appears to have been the call in
which it crashed :-(
