Hi. I believe this bug to be essentially the same as the one regarding network access.
Chris downgraded the other bug to "important" because he was filing serious bugs on the only basis that there was "network activity". In this case, however, network access (and to be precise, expecting a reply from the other side) is what makes the package to fail (it seems). My recommendation: Please find the way to disable any tests which perform network access, I have the strong feeling that the build would never hang if those tests are disabled. Thanks.
