signon fails tests on Qt 5.6

Reproduced with silo 24. Investigating...

Filed https://bugreports.qt.io/browse/QTBUG-55087

Still at least some failures with the https://codereview.qt-project.org/#/c/167480/ included:

https://launchpadlibrarian.net/279618257/buildlog_ubuntu-xenial-armhf.signon_8.58+16.04.20151106-0ubuntu2+t1~~testrebuild1~~testrebuild1~1~x2_BUILDING.txt.gz

I don't think that that failure is related. It's about the dbus daemon crashing:

(dbus-test-runner:7274): libdbustest-CRITICAL **: DBus Daemon exited abruptly!

And unfortunately it's something I've been occasionally seeing in different projects of mine in the last few months. It could be a regression in the dbus daemon itself, or maybe some issue with our builders (maybe OOM?).

Can you try building it again?

Rerun(ning) at https://launchpad.net/~canonical-qt5-edgers/+archive/ubuntu/qt5-beta2/+build/10632384

It failed but no log since LP hanged befor saving the log.

Reportedly the hangings now mean that some test process is left hanging so the build never "finishes".

The silo 42 version of signon now passes build against Qt 5.6.1 with the added commit from upstream: https://launchpad.net/~canonical-qt5-edgers/+archive/ubuntu/qt5-beta2/+sourcepub/6829102/+listing-archive-extra

  [ Dmitry Shachnev ]
  * Backport some upstream patches to add support for D-Bus global menus,
    and improve support for D-Bus tray icons (LP: #1612767):
    + dbustray_use_separate_connections.diff (fix for multiple tray icons)
    + dbusmenu_exclusive_groups.diff (fix for radio actions)
    + qplatformmenubar_createmenu.diff (adding a method to QPlatformMenuBar)
    + dbusmenu_global_menu.diff (add support for D-Bus global menus)
  * Add a distro patch to stop setting AA_DontUseNativeMenuBar unconditionally
    (allow_native_menubar.diff): we want this attribute to be false by default,
    but applications should be able to override it.
