Another useful thing to try might be a tasklist dump (Alt-SysRq-T from a console screen, not an X window) while gphoto2 is hung. Although at this point it's not so important to know what's hung and where; it's more important to know what went wrong originally to cause the hangs. Well, we learn a little more each time...
