Bug#874077: clutter-1.0: build tests fail on Debian but pass on Ubuntu

[intrigeri]

Hi,

Reproduced on current sid.

Interestingly, this happened for:

 - 1.26.2+dfsg-3 (sid, x86-ubc-01) on September 2
 - 1.26.2+dfsg-2 (experimental, binet) on August 31
 - 1.26.0+dfsg-4 (experimental, binet) on May 9

… but did not happen for:

 - 1.26.2+dfsg-1 (sid, x86-ubc-01) on July 2
 - 1.26.0+dfsg-3 (sid, x86-ubc-01) on March 12
 - 1.26.0+dfsg-1 (sid, x86-csail-01) last Oct 9

I initially thought "oh, that's caused by a build-dep that was in
experimental earlier and uploaded to sid between July 2 and August
31", but in the failure logs on experimental I can't see any build-dep
pulled from experimental.

FWIW in a sid VM (libvirt/QEMU, GNOME on Wayland, QXL graphics so
llvmpipe is used), /usr/lib/x86_64-linux-gnu/installed-tests/clutter/*
all pass with and without the `xvfb-run -a' adverb, except
actor-layout that segfaults (in wl_proxy_add_listener, no g_strsplit
assertion failure, so probably unrelated). So I bet that the reason
why the tests fail on our buildds is caused by a more restrictive
environment than what this test suite expects.

Cheers,
