I did contact the author and he kindly has fixed this bug in December 2012.
The new package can be downloaded from: http://www.photofilmstrip.org/builds/photofilmstrip_1.9.92-1_all.deb However Jens stated that this build would need some more testing before it is released. Here, on Wheezy-amd64 all is fine. I'd recommend to pull it into Wheezy. Thanks Jens -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
