Comment # 3 on bug 990425 from Atri Bhattacharya

I Don't understand the problem, really, but here are a few comments that might
help explain what I don't understand:

1. "zypper se -t application" is a broken feature, it only shows applications
corresponding to installed appdata on a given system and randomly a few not
installed ones. So if calibre doesn't show up when it isn't installed on
zypper's application search, that may not be surprising. On my TW system
:~> zypper se -t application calibre
Loading repository data...
Reading installed packages...
No matching items found.


2. zypper se calibre
Loading repository data...
Reading installed packages...

S | Name    | Summary                      | Type   
--+---------+------------------------------+--------
  | calibre | EBook Management Application | package

So not really clear where the problem is.

Fwiw, my changes are here:
