Bug#834334: FTBFS in stretch, sid: appinfo test failures

[Simon McVittie]

Source: glib2.0
Version: 2.48.1-2
Severity: serious
Justification: fails to build from source (but built successfully in the past)

While testing the patch for https://bugs.debian.org/834272 (which does
work) I found these appinfo test failures in a local stretch sbuild
instance:

No DISPLAY.  Skipping test.  **
GLib-GIO:ERROR:/<<PKGBUILDDIR>>/./gio/tests/appinfo.c:317:test_associations: assertion failed: (result)

and

GLib-GIO:ERROR:/<<PKGBUILDDIR>>/./gio/tests/desktop-app-info.c:44:create_app_info: assertion failed: (error == NULL)

I also saw at least the desktop-app-info one in a sid sbuild instance.
However, I don't get these when building upstream glib from the 2.48
branch without using a chroot - possibly DISPLAY-related?

I've only opened one bug because they're probably related.
Looking into them now.
