Thanks Rafael, Gabriel, Philipp! Your logs agree in the fact that at the time it tries to call, or called pm-suspend, the shim's D-BUS connection goes away:

09:20:16 E: (process:3100): GLib-GIO-CRITICAL **: g_dbus_connection_flush_sync: assertion 'G_IS_DBUS_CONNECTION (connection)' failed

(and some noise around it). Rafael's log additionally shows

  15:05:35 E: ** (process:19670): WARNING **: Error while running '/usr/sbin/pm-suspend'

but not what kind of error unfortunately. At the moment I don't have an idea what happens there, I'll discuss with Ryan and try to get something like that by sprinkling some sleeps around pm-utils and the code.

Rafael and Gabriel's pm-suspend.log shows no oddities, and suspend looks fairly fast. Philipp's pm-suspend log confirms that the suspend takes some 30 seconds for him, which is absurdly long. That's yet another bug (might be in pm-utils or in the kernel); Philipp, can you please report it against pm-utils, and we debug it in another bug report?

So let's use this bug report for the broken D-BUS connection.
