Description quamis 2013-11-09 14:35:16 UTC 
Application: digikam (3.5.0)
KDE Platform Version: 4.11.2
Qt Version: 4.8.5
Operating System: Linux 3.11.7-200.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
- What I was doing when the application crashed:
saw a custom-made movie(timelapse sticked using kdenlive, so no camera movie).
clicked again on the same movie to see it again, and digikam crashed

The crash can be reproduced every time.

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

if i see the movie, then click on an image to view it, then click the movie again, everything works ok
Comment 2 Harald Sitter 2013-11-10 23:35:31 UTC 
Random guess of the day: calling QApplication::syncX from a random thread is a bad idea. Supposedly that should be outsourced to a auto (queued-when-necessary) method invcoation doing the sync. As in that particular call chain there is a need to propagate the WID to gstreamer only; whether or not we xsync immediately should not matter in this case.

Git commit 2cafb9db34ed1079eca22c913a48011b67ff9c70 by Dan Vrátil.
Committed on 08/04/2014 at 17:46.
Pushed by dvratil into branch '4.7'.

Only call QApplication::syncX() from the main thread

This fixes a regression introduced in 2db4c4. In order to pass WID to gstreamer
synchronously, a Qt::DirectConnection between Pipeline signal and a VideoWidget
slot must be created. However the signal from Pipeline can be emitted from an
arbitrary thread, so we can't call QApplication::syncX() directly from the slot
callchain. This patch moves the call to VideoWidget::syncX() slot that is called
from X11Renderer via queued invocation to make sure it's always executed from the
main thread.
