assertion G_IS_OBJECT (object) failed

[Vervaeke Jonathan <vervaeke jonathan gmail com>]

Hi everybody,


Since compiling gtk+ from source, I get the following error:


> (.:19478): GLib-GObject-CRITICAL **: g_object_get_qdata: assertion `G_IS_OBJECT (object)' failed
> (.:19478): GLib-GObject-CRITICAL **: g_object_set_qdata_full: assertion `G_IS_OBJECT (object)' failed
> **
> Pango:ERROR:pangofc-fontmap.c:2138:pango_fc_font_description_from_pattern: assertion failed: (res == FcResultMatch)


I am not able to open gnome programs, vlc, and other frequently used programs.
Found no solution googling these messages.

Can anybody help?

Thx!

Jon.
