Bug#1051783: uqm: flaky autopkgtest: savegames: Missing/invalid savegame, exit status 12

[Simon McVittie <smcv@debian.org>]

Source: uqm
Version: 0.8.0+dfsg-2
Severity: important
User: debian-ci@lists.debian.org
Usertags: flaky
X-Debbugs-Cc: debian-ci@lists.debian.org
Control: affects -1 + src:libsdl2

The uqm autopkgtest 'savegames' intermittently fails on ci.debian.net,
which the testing migration infrastructure assumes is a regression in a
package that was upgraded, preventing packages like libsdl2 from migrating
to testing until the uqm autopkgtest is retried. For example, please see:

https://ci.debian.net/data/autopkgtest/testing/amd64/u/uqm/36300400/artifacts.tar.gz

https://ci.debian.net/data/autopkgtest/testing/ppc64el/u/uqm/36877335/artifacts.tar.gz

If this test is known to be unreliable, please mark it with
"Restrictions: flaky" so that it doesn't stop other packages from
migrating.

Thanks,
