The duplicate signature was actually incomplete and missing information as 'MachineType' is not known to apport when apportcheckresume is run, rather this information is gathered by the apport package hook for linux so the duplicate signature creation belongs there.
You can see the incomplete signatures in the error tracker: https://errors.ubuntu.com/oops/73891a08-dc8d-11e3-94de-fa163e707a72 ** Changed in: apport (Ubuntu Utopic) Status: Fix Committed => Triaged ** Changed in: apport (Ubuntu Trusty) Status: Fix Released => Triaged -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to apport in Ubuntu. https://bugs.launchpad.net/bugs/1316841 Title: apportcheckresume does not create a duplicate signature Status in Ubuntu error tracker backend (daisy): Triaged Status in “apport” package in Ubuntu: Triaged Status in “apport” source package in Trusty: Triaged Status in “apport” source package in Utopic: Triaged Bug description: There is no StacktraceAddressSignature nor a DuplicateSignature in these crashes so they are never consolidated by the Ubuntu Error Tracker and subsequently do not appear in the top crashes for linux.
