SyntaxWarning: 'str' object is not callable Upon Installation on Debian bullseye

Hi,

I have a Docker image that utilizing the onboard keyboard. Upon building the image using version bullseye armhf 1.4.1-5+b3 (from debian repository), I noticed there is an error message as below. I not sure what is the impact on the onboard keyboard from this error message. There is no error message when building the image using version buster armhf 1.4.1-4+b1 (from raspbian repository).

Error Message:
/usr/lib/python3/dist-packages/Onboard/LayoutLoaderSVG.py:447: SyntaxWarning: 'str' object is not callable; perhaps you missed a comma?
 raise Exceptions.LayoutFileError("Unrecognized modifier %s in" \

Thanks & Best Regards,
Shuuri
