Comment 3 for bug 1486933

BTW I even had XFCE crash once while reproduing the above segfault.

I have almost NEVER had a linux installation that didn't fill the terminal with gtk and Glib errors.
For PCB, whenever I:

A: click on the blank canvas
B: move the mouse on to the canvas from the edge of the window.
C: let the mouse stop on the canvas and then move it

I get the following messages:

(pcb-gtk:2293): GLib-CRITICAL **: Source ID 128 was not found when attempting to remove it

(pcb-gtk:2293): GLib-CRITICAL **: Source ID 274 was not found when attempting to remove it
