Bug#941550: glib2.0: intermittent test failure on s390x: mimeapps test segfaults

[Simon McVittie]

Source: glib2.0
Version: 2.62.0-2
Severity: important

glib2.0 2.62.0-2 failed tests a couple of times on s390x, with a
segmentation fault running gio/tests/mimeapps.c.

In one failure the last output from that test appears to have been:

In a third retry, all tests passed.

I haven't tried to reproduce this on a porterbox yet. It will probably
be necessary to reproduce this bug on a porterbox and get a backtrace
before it can be fixed.
