Here:

onInstall goes straight out of scope as soon as installApp() returns, and then gets garbage collected

Thanks a bunch Chris! I thought we had a crash in this region of code. Will get the fix in today!

This bug was fixed in the package webapps-greasemonkey - 2.3.2-0ubuntu1

---------------
webapps-greasemonkey (2.3.2-0ubuntu1) quantal; urgency=low

  * New upstream release.
    - Force initialization of storage service prior to opening
      UnityWebappsRepository (LP: #1058209)
    - Save install callbacks to prevent them from being preemptively
      garbage collected (LP: #1059441)
  * debian/patches/version_bump.patch
    - bump the version of the extension, upstream missed that in the release.
