Hi,
I've found that current glom if no change rebuilt in sid fails a lot
when running its self tests.
Please do note that this might - at least partially - be caused by [1]
which happens due to [2] not yet being fixed. But since neither of
those two reports contains the signatures I've seen I thought I better
report this as well. If OTOH eventually just the fix for the python
versions fixes all three bugs that is great, but if not we have proper
bugs to track each of them.

Many of the build time tests crash, but overall there are only two
different signatures.
For the curious I attached the full build log to this mail as bzip2.

First there is something related to initdb (might be a red herring, I
tried PG-13 / PG-14 both fail the same way) eventually leading to a
segfault.

```
 locale is not properly installed or configured.
initdb: error: cannot be run as root
Please log in (using, e.g., "su") as the (unprivileged) user that will
own the server process.
virtual Glom::ConnectionPoolBackends::Backend::InitErrors
Glom::ConnectionPoolBackends::PostgresSelfHosted::initialize(const
SlotProgress&, const Glib::ustring&, const Glib::ustring&, bool):

```


Then the other more directly points to a potential relation to [1][2]
with python related error messages.

```
