Noticed when testing T5775:
After "gpgconf --kill all" was executed, hitting F5 on the smart card tab does not work: no card could be accessed.
Expected behavior: all necessary background processes restart, smart card is accessed with a bit of delay.
Debugview showed:

To get the agent to start and reading of the smartcard to succeed, you have to change to the certificate tab, press F5 there and after that F5 on the smart card tab will work again.
