title: Kleopatra No secret key
body: <p>I support an application who call a CMD line to decrypt a file.
  The application is a .exe file that is called by the Windows Task Scheduler and is execute as the same user who have all right.</p>
  
  <p>The application run every week day in the evening at 6h30pm and sometimes the CMD line return the message: no secret key.
  The application failed because the file was not decrypted. But it doesn't failed every evening, just random evening. It looks totally random. </p>
  
  <p>And if I run the application myself after it failed with the same user, it worked. </p>
  
  <p>The secret key is imported in Kleopatra and it work fine with other application that run in the morning. And it work fine when I used it.</p>
  
  <p>What can cause this?</p>
  
  <p>Thank you</p>
