Version:            (using KDE KDE 3.5.6)
Installed from:    Ubuntu Packages
OS:                Linux

Using Ubuntu 7.04, digikam 0.9.1 , KDE 3.5.6.  The Create MPEG Slideshow plugin causes the desktop to crash and restart, requiring login again.  

Select at least one image and go to Tools > Create MPEG Slideshow.  Video format VCD, video type NTSC Chroma Mode Default.  Click on Encode and get warning dialog that "Check your Mjpegtools version...Default Chroma mode only works with Mjpegtools version < 1.6.3"

Click Cancel to this and desktop crashes and restarts.  Mjpeg tools version 1:1.8.0-0.2ubuntu3 from the Ubuntu packages.

digiKam has a new Video Slideshow tool based on QtAV and ffmpeg which do not
have this problem.
