control: retitle -1 DistributionNotFound: The 'singledispatch' distribution was
not found
control: severity -1 important
This bug is now a blocker for src:python-pydap (currently under ITP).
The test suite for Pydap fails and the log is riddled with
DistributionNotFound errors regarding singledispatch:
```

```
This, plus the dh-python3 warning reported initially (when the failure
of the tests above is bypassed), is a sign of something seriously wrong
with the packaging.
