           Summary: Crash on switching between Summary and To-do within
                    Kontact
           Product: korganizer
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: korganizer-devel at kde.org
        ReportedBy: rkrell at gmx.net


Version:           4.2.1 (using 4.2.00 (KDE 4.2.0) "release 90.1",
KDE:KDE4:Factory:Desktop / openSUSE_11.1)
Compiler:          gcc
OS:                Linux (i686) release 2.6.27.7-9-default

After adding a To-do entry and switched from To-do to the Summary and back
Kontact crashed. My computer was under quite heavy CPU load (90-100%) during
that, caused by some other processes.

Backtrace:

Application: Kontact (kontact), signal SIGSEGV
