Bug#1020832: openmsx-catapult: flaky autopkgtest: "local variable 'done' referenced before assignment"

[Simon McVittie <smcv@debian.org>]

Source: openmsx-catapult
Version: 18.0-1
Severity: serious
X-Debbugs-CC: debian-ci@lists.debian.org
User: debian-ci@lists.debian.org
Usertags: flaky

The autopkgtest for openmsx-catapult seems to be intermittently failing
like this:

> Traceback (most recent call last):
>   File "/tmp/autopkgtest-lxc.7f56s1c5/downtmp/build.0aM/src/debian/tests/run.py", line 83, in <module>
>     test_detect()
>   File "/tmp/autopkgtest-lxc.7f56s1c5/downtmp/build.0aM/src/debian/tests/run.py", line 60, in test_detect
>     done.click()
> UnboundLocalError: local variable 'done' referenced before assignment

for example in
<https://ci.debian.net/data/autopkgtest/testing/amd64/o/openmsx-catapult/26482312/log.gz>
and
<https://ci.debian.net/data/autopkgtest/testing/amd64/o/openmsx-catapult/26287741/log.gz>.

When testing a proposed update to a package it depends on (such as dbus
and gcc-12, in this case), a test failure like this is assumed to be a
regression in the updated package, which can delay or prevent testing
migration.

Please look into whether this test can be made reliable, or if it cannot,
mark the test with "Restrictions: flaky" so that it doesn't disrupt other
packages.

In this case I suspect this is a bug in the test script rather than the
upstream code.

Thanks,
