  errors.ubuntu.com [1] is showing a high crash rate in GNOME Software. This 
appears to be due to apt updates occuring outside of GNOME Software and 
triggering access of a NULL pointer inside appstream-glib. Upstream fixed this 
crash by correctly handling the NULL pointer in appstream-glib 0.7.0. I have 
not been able to locally reproduce the issue.

  [Test Case]
  1. Run GNOME Software

  Expected result:
  This crash doesn't show in errors.ubuntu.com.

  Observed result:
  This crash shows in errors.ubuntu.com.

  [Regression Potential]
  Low, the fix is a simple check for a NULL value. It is already running this 
way in 17.10 (no significant errors showing there).

[Jean-Baptiste Lallement]

@Brian, could you verify if the crash is still received by the error
tracker for this version? I verified the other part of the SRU (bug
1700994)

Thanks.

[Brian Murray]

The linked to bucket in the Error Tracker shows the crash being about
gnome-software so when verifying the fix in the Error Tracker we should
query the instances in the bucket to find out if the new version of
appstream-glib appears in the Dependencies. Ping me when its time to
release this and I'll run the right query.

[Desktop-packages] [Bug 1675633] Re: gnome-software crashed with SIGSEGV in as_format_get_kind()

[Robert Ancell]

The crash seems to be due to the package list being reloaded outside of
GNOME Software. An inconsistency inside AppStream has a package with a
NULL value for format, and the crash occurs accessing that.

- I used the software & updates tool to select the fastest server for me
