Thanks for the hint. It seems it works once I enable
QTEST_FUNCTION_TIMEOUT. The value of it I just follow the [2] to set
`900000` milliseconds (15 mins). But I am not sure the value is okay
for you.:)

I do not attend one debdiff file because now I have trouble to build
it on sid-riscv64-sbuild. Once done, I will update it here.

Thnak you,
BR,
