It’s likely that LP virtual builders for x86 are on trusty (or an older ubuntu release anyway), this /dev/shm issue started appearing in vivid, which would explain why we’re not seeing it in PPA builds.
Of course when LP builders are upgraded to vivid(+n), builds will start failing. If we can devise an acceptable solution for the vivid chroots used by CI, then we should be able to apply it to LP as well.
