    thumbnails: avoid crash with jp2 images
    
    When thumbnailing a directory with jp2 some times nautilus
    was crashing.
    However tests on gdk_pixbuf were successful and gnome-desktop-thumbnails
    generation tests were also working.
    
    Also, nautilus is using raw pthreads in the thumbnail generation
    code, and seems the crash was actually only happening when inside the
    pthread and when using gdk-pixbuf, not only the gnome-desktop-thumbnail.
    
    Looking at the implementation of glib in threads and nautilus, one of
    the differences is that nautilus sets a stack size.
    The crash is happening because, unluckely, libjasper with some big
    images is using more stack size than the one nautilus is setting, which
    leads to a crash in libjasper.
    
    To fix it, remove the stack size set by nautilus, similarly to what glib
    does, not setting an actual stack size.
    
    Obviously the right thing to do is rewrite nautilus code to use the
    glib threads, but I want to let that as a newcomer bug to do.
