** Summary changed:
- copy/paste trace
+ ugly trace when copy/pasting in a custom gtk.TextView
** Description changed:
- Do a copy/paste in a task then close GTG :
+ In the GTG software, we are using a custom TaskView who inherits from
+ gtk.TextView. TaskView has its custom serialization/deserialization
+ functions.
+
+ When copy/pasting in our TaskView, we got the following ugly trace (but
+ the program is not always crashing. Sometime the trace appears only
+ after you close the whole program).
+
+ Even if we are doing something bad, we should never see this trace as we
+ are doing pure python work.
+
+ If you want to reproduce this bug, you can :
+ - bzr branch lp:gtg
+ - launch ./debug.sh
+ - create a new task with some text in it
+ - copy paste the text in the same task
+ - if the application didn't crashed, just close it, you will see the trace
