[Debian/buster] Problems after Upgrade 4:5.13.1-1 to 4:5.13.4-1

[Sedat Dilek <sedat.dilek@gmail.com>]

Hi,

my "quick-starter" is gone - the panel with the mini-programs like
network-manager, discover (showing upgradable packages) etc.

Trying to re-add the "quick-starter" (German "Schnell-Starter") via
"add mini-programs" fails.
Adding a different mini-program like "memoory status" (German
Speicherstatus) is OK.

Is there a known issue with that?
Any workarounds you know?

Thanks in advance.

Regards,

P.S.: My system is a Debian/buster AMD64.
