I guess this can happen if your python source files are accessible
through symlinks?
Yes, that turned out to be the situation in the cases I encountered. There are probably other ways a file can be found via multiple paths, like hardlinks and multiple mounts of a filesystem.

I think this should be conditional on (or find-file-existing-other-name
find-file-visit-truename), which is what find-file-noselect checks for.
No, as far as I can tell, that doesn't hold in this situation.
The point of this issue is to not delete a source file that was already present in the editing session before the pdb-tracking debugging process stepped through code in the file. The prior presence of the file should be respected regardless of the settings of find-file-existing-other-name or find-file-visit-truename, so these settings should not be considered for this comparison.
