Description krienke 2007-02-20 08:01:54 UTC 
Version:           0.9.1-rc1 (using KDE KDE 3.5.6)
Installed from:    SuSE RPMs
Compiler:          gcc 4.1.2 
OS:                Linux

When a comment in a photo is longer than about 60 characters and this photo is shown using the new great slideshow tool then this comment is tuncated (actually "..." replaces the rest of what is not shown) when displayed in the slide show.  

Actually the comment should be displayed as is and not be truncated. When a photo is in portrait orientation there really is no need to truncate the comment at all, since there is room enough beneath the photo. If the photo is in protrait orientation, the comment should be formatted into several lines.
