gdk_pixbuf_save JPEG error!

["Mr antback" <antback gmail com>]

Hello all!

I have an application that saves images as JPEG. The code is simple and it worked right
before than the last Thursday, when I updated the libgtk2 libraries on my kubuntu distribution.
From these day, I cannot save images in JPEG format. The following code, works:

    retval = (PRBool) gdk_pixbuf_save (image, mFilename.get(), "pgn", &error, NULL);

But the following

    retval = (PRBool) gdk_pixbuf_save (image, mFilename.get(), "jpeg", &error, NULL);

terminates the application like this:

    Program exited with code 01.

The program, links against these libraries:

/usr/lib/libgdk_pixbuf-2.0.so.0 -> libgdk_pixbuf-2.0.so.0.1000.6
/usr/lib/libgdk-
x11-2.0.so.0 -> libgdk-x11-2.0.so.0.1000.6
/usr/lib/libgtk-x11-2.0.so.0 -> libgtk-x11-2.0.so.0.1000.6
/usr/lib/libgnomevfs-2.so.0 -> libgnomevfs-2.so.0.1600.1

and gdk-pixbuf-query-loaders seems to be good:

"jpeg" 5 "gtk20" "The JPEG image format"

Any idea about the problem?
