[Bug 294884] New: Digikam crash at startup (due to notification window)

https://bugs.kde.org/show_bug.cgi?id=294884

           Summary: Digikam crash at startup (due to notification window)
           Product: digikam
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Application: digikam (2.6.0-beta2)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.2.7-1.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I just started digikam

According to the trace, the crash is related to the notification window.
I may add that I am quite "frenetic" with my desktop (Gnome 3), and the crash
seems to occur when I start digikam, then immediately do something else.
If I wait for digikam to start, then for the task that scan new items to finish
properly, nothing bad happens.

The crash can be reproduced some of the time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Sorry, the automatic bug report tool did not include all the usual stuff :
-OS : fedora 16 (fully updated)
-Desktop : Gnome 3
-digikam : built from source (latest git as of yesterday evening)

As You suggest, I'm actually not sure this bug is relative to digikam, and I
don't use many other Qt-based software, so I can't say for the others.

Git commit cd6c2eb59770eb3f1379ece36fabddb5aef13620 by Marcel Wiesweg.
Committed on 01/03/2012 at 22:17.
Pushed by mwiesweg into branch 'master'.

Do not crash if null parent is given to notification wrapper

This can happen at startup. We could use the desktop window then, but I believe
putting a notifier just somewhere is more wrong than right, better skip it
then.
