Hello,

after the 8b6e9acc268501223a231d50932192f6bb69d34d I cannot pull my
personal channel.  With the channel definition of

The build log contains the following:

--8<---------------cut here---------------start------------->8---

Though parent commit fails as well, the error is different and it was
fixed in #71979.  With the 8b6e9acc268501223a231d50932192f6bb69d34d
reverted, I can pull current master fine.

I would consider just reverting the commit, since, even on the parent,
the reproducer in the commit message seems to work fine:

Hm.  I'm not sure.  I haven't tried reproducing, I trust your
conclusion.  I remember coming with this fix in a hurry; possibly there
was some stale byte code in my tree that was throwing things off.

Reverted in ea4dd4c45d9.  If some regression rears its head we'll have
to sit down and think of a better fix :-).

Apologies for the delay!
