Kleopatra crashes (segfaults) when doing a lookup on server and a certain number of results are found.
How to reproduce:
- Use the default key server (hkps://keyserver.ubuntu.com)
- Open Lookup on Server
- Enter example
- Press Return or click Search
-> boom

$1 = std::shared_ptr<_gpgme_key> (use count -238808599, weak count 32766) = {get() = 0x4009}ebo reproduced the crash on Windows.
The crash occurs in a call of std::sort() that was introduced for T7067: Kleopatra: Add origin information in search results. I suggest to revert the changes made for T7067 for VSD 3.3. For T7153: Kleopatra: Show all search results (from different origins) we will anyway have to rewrite the result view because the standard certificate list doesn't support multiple keys with the same fingerprint.
