Public bug reported:

Binary package hint: ffmpegthumbnailer

er ... thumbnailer crashes on some specific videos. Pictures work fine.

1) Ubuntu 9.10
2) Package version: 1.5.4-1build1
3) ffmpegthumbnailer should create the thumbnails without stopping
4) ffmpegthumbnailer stopps at a certain file - after some time (~1-3 minutes) the crash information appears. Often I use to kill the process of ffmpegthumbnailer.
