Bug#737054: oss-compat: deadlocks during remove

[Andreas Beckmann]

Package: oss-compat
Version: 5
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

during a test with piuparts I noticed your package fails to remove,
the apt-get command gets killed after a timeout and there are two
processes running that probably didn't terminate as expected ...

>From the attached log (scroll to the bottom...):
