Re: How to properly register a program in KDE/GNOME

[Eric Lavarde <deb@zorglub.s.bawue.de>]

Hi,

I now know why it's not working, it's because I'm testing under KDE 3.5 
(Lenny) and it makes a difference for xdg-utils!

OK, here it is:

- under a sid chroot, i.e. without Desktop environment:
$ DISPLAY=:0 XDG_UTILS_DEBUG_LEVEL=100 xdg-mime query filetype New\ 
Mindmap.mm
Running /usr/bin/file -i "New Mindmap.mm"
application/x-freemind; charset=us-ascii

$ DISPLAY=:0 XDG_UTILS_DEBUG_LEVEL=100 xdg-mime query default 
application/x-freemind
Checking /home/ericl/.local/share//applications/defaults.list
Checking /usr/local/share//applications/defaults.list
Checking /usr/share//applications/defaults.list

- under Lenny/KDE 3.5.9 (same file):
$ XDG_UTILS_DEBUG_LEVEL=100 xdg-mime query filetype New\ Mindmap.mm
Running kfile "New Mindmap.mm"
text/plain

$ DISPLAY=:0 XDG_UTILS_DEBUG_LEVEL=100 xdg-mime query default 
application/x-freemind
Running ktradertest "application/x-freemind" Application

kfile and ktradertest belong to package kdelibs4c2a, and looking at the 
bugs assigned to this package, it doesn't seem to use the freedesktop 
standard for mime types, as many people are asking to get their mime 
type added to the central database. I guess that it's using 
/usr/share/mimelnk as provided by kdelibs-data.

So, basically, under Lenny/KDE, xdg-mime uses an application that 
doesn't use the XDG framework... Sounds like a bug, no?

Furthermore, regarding now under Sid/console, xdg-mime is using 
/usr/share/applications/defaults.list to find the right application; 
this file is supposed to be created by update-desktop-database (part of 
the desktop-file-utils package); this call is supposed to be added to 
packages through dh_desktop, but man dh_desktop under Sid tells me that 
it's obsolete and doesn't do anything.
Sounds like a big bunch of spaghettis!?

Do you agree that we have here 2 bugs lurking around?

Thanks, Eric
