Always hard to localize error causing line

[buhtz]

I get errors like this:

reading sources... [100%] tools

/home/user/goodCloud/my.work/bit/backintime/common/snapshots.py:docstring of snapshots.Snapshots:4: WARNING: Inline literal start-string without end-string.
looking for now-outdated files... none found

But line 4 in that file is not the cause. I don't get it how Sphinx does the line numbering.
This is the original file: https://github.com/bit-team/backintime/blob/dev/common/snapshots.py

Does anybody has an idea? I also would like to understand the Sphinx logic to prevent questions like this in the future and find the error line myself.

The line points to the start of the paragraph containing the error -- this is a known issue.

A

Can you link the issue please if it is "known".

The line points to the start of the paragraph containing the error

I don't understand. What is "4" in this case?

Please re-open the thread. It is not solved for me.
It is still unclear for me which one of the doc strings in that file is the cause of the problem.
