segmentation fault when trying to save a pixbuf into a file

[y g <odysseus lost gmail com>]

Hello,

I had posted in the past but with no luck about segmentation faults
that I am getting when trying to save a pixbuf into a file. With a bit
more debugging this is the error I am getting when I try:
gdk_pixbuf_save(pixbuf, "temp.bmp", "bmp", NULL);

Program received signal SIGSEGV, Segmentation fault.

As a first sign I am noticing that
~/Downloads/gtk2.6/glib-2.6.4/glib/gstrfuncs.c:90:2850:beg:0xb9d8c5
are the extracted files when I installed gtk2.6. I was quite sure that
I had setup my environment variables properly:

CPATH=/opt/gtk-2.6/include:/opt/gtk-2.6/include:atk-1.0:/opt/gtk-2.6/include/glib-2.0:/opt/gtk-2.6/include/gtk-2.0:/opt/gtk-2.6/include/libglade-2.0:pango-1.0:$PSG/include:/usr/local/include:/usr/include:$LOCAL/include:$CPATH

PLAYERPATH=$PSG/lib:$PSG/lib/python2.3/site-packages
CPPFLAGS=-I/opt/gtk-2.6/include
LDFLAGS=-L/opt/gtk-2.6/lib

Anyone any clues?
