However, when mplayer was installed it printed the name of a file it was playing. This file is a jpeg file but had no file extension. When I renamed the file and added in the .jpg extension, the segfault went away. Note that the file must be in a subdirectory, eg in the settings: MythGallery Settings (General) Directory that holds image: /data/pictures I have just one jpeg file in a subdirectory, called /data/pictures/crashy/wsf which causes the seg fault. The segfault occurred with different jpeg files for me. ",Bug Report - Crash,closed,minor,unknown,Plugin - MythGallery,0.23-fixes,high,Works for me,,,0
