Bug#709197: More GLib-CRITICAL **: messages produced by networking applications

[Ingo]

package: libglib2.0-0
severity: important

All Debian-Jessie-amd64 with XFCE-desktop.
Happens on both, freh installs and also on uprgades from Wheezy.

It's not just Iceweasel, the very same message is generated on every
startup of Icedove:
GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

Following message is generated on every download of weather-data
(happens every 20 min.) by xfce4-weather-plugin 0.8.3-2
(wrapper:3061): GLib-CRITICAL **: Source ID 7763 was not found when
attempting to remove it

These messages come in blocks of 4 lines from xfce4-netload-plugin
1.2.0-1 when changing properties and closing the settings dialogue:
(xfce4-netload-plugin:1679): GLib-CRITICAL **: Source ID 167 was not
found when attempting to remove it

There are some other bugs which assign similar problems to the
applications which trigger it, i.e: #782536. But appearently this all
points to libglib2.0 + glib-networking-services.

As this all happens in Debian-stable I'd suggest to raise severity to
"important".
