           Summary: parley: Segmentation fault when switching between list
                    view and start exercise dialog
           Product: parley
           Version: unspecified
          Platform: Debian testing
        OS/Version: unspecified
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: parley-devel at kde.org
        ReportedBy: ewoerner at kde.org


Version:            (using KDE 4.3.4)
Installed from:    Debian testing/unstable Packages

This bug has been forwarded from
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=562955

Howto produce the Segfault:

1. Start parley and install any vocabulary. If you have already a vocabulary
installed this is fine too.

2. Open a collection for editing by pressing the "Edit" button behind a
collection in the list "Last Opened Collections". The "Last Opened Collections"
list is displayed in the main Window.

3. Leave the edit mode by entering File->close (<ctrl>+w)

4. Start an exercise by pressing the "Practice" button behind a collection in
the list "Last Opened Collections".

5. In the "start practice" dialog just press "cancel".

6. Back in the main window try again to open the edit view by pressing the
"Edit" button (step 2). You will get the Segfault.

Here is the crash dump from KDE crash manager.
