example: darktable from home:darix:darktable:master

package provides: /usr/share/appdata/darktable.appdata.xml

but the repository does not provide an appdata data file.

so zypper shows me:

The following 3 applications are going to be REMOVED:
   "Wireshark (GTK) Network Analyzer" "Wireshark (QT) Network Analyzer"
darktable

for the darktable part according to dimstar the following happens:

1. zypp sees the file has an appdata file installed
2. the repository doesnt provide appdata information
3. assuming deinstallation.

correct would be

1. zypp sees package comes from repository without appdata information
2. zypp skips all app data related checks

then we wouldnt print false information that the "app" gets uninstalled. (in
the package list it is correctly shown as package that will be updated.)

for the wireshark related subpackage dimstar is unsure why it complains at all.
the appdata information file lists e.g. <id>wireshark-qt.desktop</id>
