Package: gnome-splashscreen-manager
Version: 0.2-12
When I invoke `gnome-splashscreen-manager' it fails with an error Unrecognised
image file format (Gdk::PixbufError)
This is the complete output:

The image file of the downloaded splashscreen is corrupted but I think that it
is wrong to break the whole program.
It would be right to automatically remove the corrupted entries and continues
it's lifecycle.
The problem is on the download_pixbuf method of the splash_screen.rb script.
The loader throws a Gdk::PixbufError if the file is not a correct image file
(from a corrupted download maybe) and this exception is unhandled. This method
is used by the create_thumbnail method to read the image and create the
thumbnail for the program's main window.
So because the MainWindow.rb constructor at start reads the
#{Home_dir}/#{Gnome_dir}/splash-screens.xml and creates the thumbnails
of the image files, it goes down..
You can reproduce it very easy, just add a <splash_screen> entry at
#{Home_dir}/#{Gnome_dir}/splash-screens.xml file and touch the file you
entered for filename in the entry. The file is not a correct image file
and the whole thing will fail.
I think that the solution is pretty simple but I 'm a java developer at
most and not at all familiar with ruby (so maybe there is a more
sophisticated way to handle this situation), what I did to fix it is:
1) changed the splash_screens.rb script at line 190 to add an exception
handler and return nil on error:
old code snippet:
loader = Gdk::PixbufLoader.new
open(url) { |f|
loader.last_write(f.read)
}
new code snippet:
begin
loader = Gdk::PixbufLoader.new
open(url) { |f|
loader.last_write(f.read)
}
rescue
puts "Error in image file format: "+url
return nil
end
2) edit the splash_screens.rb again into method create_thumbnail (line
205 with the new code snippet) and added between pixbuf =
download_pixbuf(url) and pixbuf.scale(130, 90,
Gdk::Pixbuf::INTERP_BILINEAR) this code snippet:
if (pixbuf == nil)
return nil
end
That's it. Now the reload_splash_screens method that runs at start of the
program will load the thumbnails and every nil thumbnail will be deleted from
your #{Home_dir}/#{Gnome_dir}/splash-screens.xml file with a notification
message at standard output to delete the image file manually from your
filesystem.
I am using Debian GNU/Linux 5, kernel 2.6.26-1-amd64, gnome 2.22.3
