Description Cor 2015-07-05 15:12:21 UTC 
If I start digikam, the application doesn't get past the splash-screen. If I run the application from command line I get this:

Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 14: reading configurations from ~/.fonts.conf is deprecated.
digikam(3468)/digikam (core) Digikam::CollectionScanner::scanAlbum: Folder does not exist or is not readable:  "/home/cpt/large/Pictures/lost+found" 

(digikam:3468): GLib-GObject-WARNING **: cannot register existing type `GstObject'

(digikam:3468): GLib-CRITICAL **: g_once_init_leave: assertion `result != 0' failed

(digikam:3468): GLib-GObject-CRITICAL **: g_type_register_static: assertion `parent_type > 0' failed

(digikam:3468): GLib-GObject-CRITICAL **: g_object_newv: assertion `G_TYPE_IS_OBJECT (object_type)' failed


Reproducible: Always

Steps to Reproduce:
1. call 'digikam'  on commandline
2. press Enter
3.

Actual Results:  
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 14: reading configurations from ~/.fonts.conf is deprecated.

Not relevant of digiKam digiKAm do not use Glib as well. It's a Qt application. This is probably a sub component from your system, as Phonon or GStreamer.

digiKam 5.4.0 bundles will use QtAV framework instead Qt5Multimedia to thumb
and play video/audio. The Slideshow tool will also support video as well.

QtAV use ffmpeg codecs. It's multi-platform and will always available in
OSX, Windows and Linux bundles that digiKam team provide.

For Linux packagers, you will need to turn on video support at compilation time
and solve QtAV dependencies...
