For example, when opening an existing .desktop file with: Icon=mozillafirefox-bin-icon.png The icon is not found by the icon editor, even though it exists and is visible via xfdesktop. Button text in the editor just says "No icon".
Aye, broken .desktop files. ;-) I'll fix that.
Fixed with revision 21622. 2006-05-11 Benedikt Meurer <benny@xfce.org> * exo-desktop-item-edit/main.c(main): Handle broken Icon values with file extensions properly. Bug #1795.
Not broken - sounds perfectly allowed to me: "Icon to display in file manager, menus, etc. If the name is an absolute path, the given file will be used. If the name is not an absolute path, an implementation-dependent search algorithm will be used to locate the icon. Icons may be localized with the Icon[xx]= syntax." (http://standards.freedesktop.org/desktop-entry-spec/latest/ar01s04.html) Either way, works fine now.
