udisksctl crashed with SIGSEGV in g_option_context_get_help()

[Martin Pitt]

Just "udisksctl help" triggers this in current wily. This sounds like a glib regression or some other ABI change, as this command still worked on the last udisks upload.

Hi Martin,
  Yes, there was something screwy about apport as well; it did bring up a dialog saying that something had gone wrong and I told it to report it, but didn't manage to make it through to launchpad (it brought up a web page saying I was already logged in and I couldn't get it further).

This works fine under vivid with glib 2.44.1. Merely upgrading to wily's glib2.0 on vivid introduces this crash.

Fixed upstream: http://cgit.freedesktop.org/udisks/commit/?id=410cab8f3d749ad2660cda3ba38b6aece42bf10f

[Launchpad Janitor (janitor)]

This bug was fixed in the package udisks2 - 2.1.6-2

---------------
udisks2 (2.1.6-2) unstable; urgency=medium

  * Fix udisksctl help crash with glib 2.45. (LP: #1478369)
