I thing there is bug in image dimensions handling (may return zero in some cases).
pixbuf = gdk_pixbuf_loader_get_pixbuf (loader);
width = gdk_pixbuf_get_width (pixbuf);
height = gdk_pixbuf_get_height (pixbuf);
if (width >= height) {
if (width > 48) {
ratio = width / 48;
width = 48;
height = height / ratio; (1)
}
} else {
if (height > 48) {
ratio = height / 48;
height = 48;
width = width / ratio; (2)
}
}
If ratio is bigger than height(1) or width(2) it might end as 0.
I have patch that hacks it.
Backtrace:
