Description

I noticed this when trying to decrypt a file on Windows by drag + drop on the Kleopatra icon.
Kleopatra was not running before.
The decrypt/verify window opens for 1-2 seconds and then disappears again. No Kleopatra window shows, no info for the user.

Debugview shows:

574	3653.045555	5372	kleopatra.exe	org.kde.pim.kleopatra: Using: "C:/Users/g10code.WIN-TEST3/AppData/Local/Temp/kleopatra-oFJiTO" as temporary directory.

579	3653.354873	5372	kleopatra.exe	org.kde.pim.kleopatra: Collection Progress:  1000  total:  1000

The temporary folder given in the output there exists and contains the decrypted file.

This can also be reproduced by calling on the command line with the to-be-decrypted file as argument on Windows and Linux.
