paperwork: autopkgtest armhf regression: Libinsane item->get_options() error: 0x40000006, I/O Error (7)

[Graham Inggs]

From https://bugs.debian.org/983515

Source: paperwork
Version: 2.0.2-2
X-Debbugs-CC: <email address hidden>
Severity: serious
User: <email address hidden>
Usertags: regression

Dear maintainer(s),

With a recent upload of paperwork the autopkgtest of paperwork fails in
testing when that autopkgtest is run with the binary packages of
paperwork from unstable. It passes when run with only packages from
testing. In tabular form:

                       pass fail
paperwork from testing 2.0.2-2
all others from testing from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration to testing [1]. Can
you please investigate the situation and fix it? Your package is further
blocked because you added new packages. Since the start of the soft
freeze, source packages with new binary packages are no longer allowed
to migrate to bullseye.

Status changed to 'Confirmed' because the bug affects multiple users.

[Bryce Harrington (bryce)]

It appears Debian has worked around this by setting LIBINSANE_WORKAROUND_DEDICATED_PROCESS=0 in debian/tests/unittests. We could try doing similarly, or just sync 2.0.3-2 from Debian unstable.

https://salsa.debian.org/openpaperwork-team/paperwork/-/commit/057775a596c877b886192d70965ed27d4cb4ed34

I've filed a syncpackage for impish, however I suspect it's too late for its inclusion.
When JJ's archive opens, I believe 2.0.3-2 should automatically sync in, and this bug report can be closed at that point.
