Subject: Calling loader.close() before pixbuf assignment to avoid NoneType pixbuf

In the case loader.close() has more parsing to do, get_pixbuf() can
return a NoneType which causes issues in the snapshot view. Calling
loader.close() before this allows for proper cleanup before calling
get_pixbuf().
