Since this happens in testsuite/, my suggested workaround is to simply disable the offending call, responsible for a diagnostic message.

To-do is to submit a proper fix upstream, which likely involves overloading the << operator for the offending types.

The issue has been reported upstream, but they don't seem to have addressed it yet.

Sponsored to the kinetic unapproved queue. Thanks!

We have a fix in latest sane-backends for this issue. You may wish to pull the change and perhaps drop the patch.

[Nathan Teodosio (nteodosio)]

Since the bug didn't affect the user base directly, only testing, we will wait for a sync with Debian. Thanks, Ralph!
