Comment from: Adam Lydick <lydickaw (at) ruffledpenguin (dot) org> LB's icon resolving code sometimes returns null (I assume this is when a app was not assigned an icon, but has a desktop entry). This causes a segfault in lb_get_pixbuf_from_icon_name (lb-utils.c). I added some null/empty checking as a quick fix. This seems to work, because when the function returns null, LB handles it by substituting a default "application" icon. GdkPixbuf * lb_get_pixbuf_from_icon_name (const gchar *icon_name) { GdkPixbuf *pixbuf; gchar *tmp, *dot; GError *error = NULL; /* return null if we get a null or empty string */ if (icon_name == NULL || icon_name[0] == '\0') return NULL; /* Handle absolute paths. */ if (icon_name[0] == '/') { return gdk_pixbuf_new_from_file_at_size (icon_name, 64, 64, NULL); } }
