do-partial-upgrade crashed with SIGSEGV in pango_glyph_item_iter_next_cluster()

[Edward Donovan]

Updating Quantal today, I ran update-manager and picked 'Partial Upgrade'. It ran through its progress stages for a while, then crashed. Can't think of any other suspicious circumstances.

Apport crashed with bug 1017338 while reporting this. But the report went on to open Launchpad. I'm not totally sure what all the reported info should be, so I don't know if any was dropped. Thanks.

Ugh, I hate private master bugs.

(I like the retracer, though. :)
