Debian Buster uptodate and with systemd.
tdewalletmanager-trinity_4%3a14.0.7~pre8-0debian10.0.0+4~a

The walletmanager does not start automatically, when TDE is started.
Starting it manually with [tdewalletmanager --tdewalletd] yields an
icon in the taskbar, the wallets however never get opened not to speak
of, that they stay completely empty.
The tdewalletrc contains:
[   ]
[Wallet]
Close When Idle=false
Close on Screensaver=false
Default Wallet=Peter
Enabled=true
First Use=false
Idle Timeout=10
Launch Manager=true
Leave Manager Open=false
Leave Open=false
Prompt on Open=true
Use One Wallet=true
[   ]
Where should I look for a misconfiguration or wrong/insufficient 
permissions?

Tks and regards.
