rage v0.10.0 seems to break stuff

On the docker-based integration tests, I now get an error with the following message (after hacking the code to actually see this message):

  Error: Tried to reset after the underlying buffer was exceeded.

This occurred during the execution of the:

  swh alter recovery-bundle restore [...]

in docker test test_alter.py:test_fork_restored_in_postgresql

(note: it also occurs in swh-alter's unit tests after upgrading the rage executable).
