A debian user reported that when horizontally resizing the configuration dialog for the simple splash engine, the button that opens a gtk dialog for choosing an image is resized instead of the text box right to the left or it. See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=408445 . Also found in current svn.
Fixed with revision 26399. 2007-11-28 Benedikt Meurer <benny@xfce.org> * engines/simple/simple.c: Fix dialog layout. Bug #3287.
