           Summary: Kontact crashes when the KMail component is disabled
                    and after going to Settings, enabling the Mail
                    component and selecting one of its siblings
           Product: kontact
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: andresbajotierra at gmail.com


Here using:

Qt: 4.5.0-rc1
KDE: 4.2.63 (KDE 4.2.63 (KDE 4.3 >= 20090212))
kdelibs svn rev. 927117 / kdebase svn rev. 927117
kdepim svn rev. 928042
on ArchLinux i686 - Kernel 2.6.28.4

Kontact crashes when the KMail component is disabled and after going to
Settings, enabling the Mail component and selecting one of its siblings

Not sure if its a KMail bug or a KDELibs one (for allowing me to click on the
KMail siblings if they aren't ready to be shown)

Steps to reproduce:

- Open Kontact
- Go to Configure Kontact
- Disable the KMail component
- Close Kontact

- Re-open Kontact
(the KMail component is disabled and it doesn't appears on the sidebar)
- Go to Configure Kontact
- Enable the KMail component
- Without accepting, click on one of the KMail siblings in the configuration
dialog to show its configuration page

Kontact crashes with the following backtrace:

Application: Kontact (kontact), signal SIGSEGV
