See for example: https://bugzilla.redhat.com/show_bug.cgi?id=1739634

The package cannot create SRPM:

```
$ fedpkg srpm

error: Bad source: .../python-chm/pychm-0.8.4.1.tar.gz: No such file or directory
Could not execute srpm: Failed to execute command.
```

And hence it was not rebuilt since Fedora 29:

But no FTBFS bug was reported.
