glib logging from unity-panel-service is never seen in ~/.xsession-errors

[Daniel van Vugt]

I realized a while ago that g_debug, g_warning etc had no effect if called from unity-panel-service. unity-panel-service has always contained such calls, but the output mysteriously never appears in ~/.xsession-errors

The problem seems obvious -- it's stdout (1) and stderr (2) descriptors are closed:

ls -l /proc/`pidof unity-panel-service`/fd
total 0
lrwx------ 1 dan dan 64 2011-07-25 15:10 0 -> /dev/null
lrwx------ 1 dan dan 64 2011-07-25 15:10 1 -> /dev/null
...
lrwx------ 1 dan dan 64 2011-07-25 15:10 2 -> /dev/null
...

WORKAROUND:
Open a Terminal and run this:
  env PANEL_USE_LOCAL_SERVICE=1 unity --replace
Then you will see all the missing messages in the terminal.

Hmm, no quick fix I can see. Closing stdout/stderr appears to be a "feature" of g_dbus_proxy_new_for_bus etc.
