I think I've checked in a fix for the ODG bug
[ 1489961 ] Autopackage: crash on save as ODG
However, since it wasn't actually crashing on my system, I'm not sure
it fixes 100% of the problem.
Can anyone who's seen the crashing first verify that they still have
a crash upon saving .odg, and then update to the latest changes and
check that it solves all of the crashing?
