Comment 5 Vincent Untz 2008-12-02 23:26:35 UTC 
Happening when get_current_slide() returns NULL.
Comment 6 Vincent Untz 2008-12-05 02:16:28 UTC 
Most probably happening because there were no slides in a slideshow.
Comment 7 Vincent Untz 2008-12-05 02:48:53 UTC 
I've fixed the issue, but I'm not it was the only one. Given that the duplicates are all for 2.22, I think this commit also helps:
