Bug#1081437: gnome-settings-daemon: frequent test failure: timed out waiting for a reader on klass.display_name_fifo

[Simon McVittie]

Source: gnome-settings-daemon
Version: 47~rc-1
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

In several of the buildd builds, test-xsettings fails with:

> Traceback (most recent call last):

(Not the same failure mode as the other FTBFS I reported, although they
might share a root cause.)
