Bug#1089101: "webcamoid: Webcamoid fails to run"

Dear Sirs,

Under Debian Sid, I cannot install webcamoid:

duane@DuanesSpectre16:~$ sudo apt install webcamoid 
[sudo] password for duane:  
Solving dependencies... Error!   
Some packages could not be installed. This may mean that you have 
requested an impossible situation or if you are using the unstable 
distribution that some required packages have not yet been created 
or been moved out of Incoming. 
The following information may help to resolve the situation: 

Unsatisfied dependencies: 
 webcamoid : Depends: qml6-module-qtgraphicaleffects but it is not installable 
             Depends: webcamoid-data (= 9.4.0-1) but it is not going to be installed 
             Depends: webcamoid-plugins (= 9.4.0-1) but it is not going to be installed 
             Depends: libavkys9 (>= 9.4.0) but it is not going to be installed 
Error: Unable to satisfy dependencies. Reached two conflicting assignments: 
   1. webcamoid:amd64=9.4.0-1 is selected for install 
   2. webcamoid:amd64 Depends qml6-module-qtgraphicaleffects 
      but none of the choices are installable: 
      [no choices]

Sincerely,
Duane Kaufman
