The following patch applied to 24.4 prevents emacs from crashing, but
results in the icons not being displayed correctly. However, messed up
icons is a far better result than a crash.

It appears that one is only allowed to pass a value of 8 for
bits_per_sample to gdk_pixbuf_new_from_data. Therefore, it seems that the
long term solution is to convert the image in  xim->data to an 8 bits per
sample image. I'm not really sure I understand what an 8 bits per sample
image is. Does that mean 8 bits per pixel?
