Reproducible: Sometimes
Comment 1 Raphael Faudou CLA 2011-11-08 07:50:29 EST 
Well, such a description seems to say that it happens very often and it is not my feedback (in most of cases it works). Could you please detail the situation on which it happens and if possible provide a procedure to reproduce ?
Comment 2 Patrick Tessier CLA 2012-10-05 12:17:52 EDT 
Can you explain which edition have you done?
Comment 3 Patrick Tessier CLA 2012-10-09 07:39:43 EDT 
If I have no response I will close it.
Comment 4 David Rabely CLA 2012-10-09 07:51:53 EDT 
This bug is too old, i never managed to reproduce it and I can't remember the edition i had done.
Can be closed.
It'll be reopened if I find the same problem on the new trunk
Comment 5 Camille Letavernier CLA 2013-02-12 03:32:55 EST 
I close the task.
