[vlc-devel] [Bug] vlc crash at start play any video (error in file modules/misc/freetype.c)

[Savin Alex]

I try to debug vlc and found:
it crash at line (in file: modules/misc/freetype.c):
fmt.p_palette->i_entries = 16;

fmt.p_palette have zero value,
and when i look at code(see below), i not see where fmt.p_palette is 
initialized.
(more detail see at http://forum.videolan.org/viewtopic.php?f=13&t=65128 )
