Pb with https://code.launchpad.net/~akretion-team/openupgrade-addons/61-to-70-document

Dear Launchpad support team,

I have pushed the branch lp:~akretion-team/openupgrade-addons/61-to-70-document yesterday evening. It worked well and I can now checkout the branch.

But the corresponding web page is broken :

https://code.launchpad.net/~akretion-team/openupgrade-addons/61-to-70-document

The web page says :
<<
Updating branch...

Launchpad is processing new changes to this branch which will be available in a few minutes. Reload to see the changes.

----

Recent revisions

This branch is empty.

Could you please try to fix this, because it is blocking my merge proposal.

Thanks in advance for your help,

Alexis de Lattre
