[Robert Ancell]

** Description changed:

- The Ubuntu Error Tracker has been receiving reports about a problem regarding 
gnome-initial-setup.  This problem was most recently seen with package version 
3.28.0-2ubuntu6, the problem page at 
https://errors.ubuntu.com/problem/9e80579a18180e27a9a2ae3a0bef59f87858bba0 
contains more details, including versions of packages affected, stacktrace or 
traceback, and individual crash reports.
- If you do not have access to the Ubuntu Error Tracker and are a software 
developer, you can request it at http://forms.canonical.com/reports/.
+ [Impact]
+ gnome-initial-setup might crash when completed, due to a double free. This 
causes a crash report to show, but the functionality to otherwise work.
+ 
+ [Test Case]
+ Check crash reports stop showing on errors.ubuntu.com
+ 
+ [Regression Potential]
+ Fix is to use correct GObject API, unlikely to cause further issues.

[Bug 1767873] Re: /usr/lib/gnome-initial-setup/gnome-initial-setup:double free or corruption (!prev)

[Robert Ancell]

Confirmed it's a double free in gnome-initial-setup - we are freeing a
string in dispose (), which can be called multiple times. Switch to
freeing in finalize () which is only called once.

[Didier Roche]

I think the issue is on the C side.

I took care to not free anything returned by sysmetrics when I'm
allocating C memory so that the callers does it. Looks like a double
free in the disposal of the report page?

(for ref: https://github.com/ubuntu/ubuntu-
report/blob/master/pkg/sysmetrics/C/libsysmetrics.go#L40)

Robert, could you have a look?
