Reproducible: Sometimes

Comment 1 Raphael Faudou

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

2012-10-05 12:17:52 EDT

Can you explain which edition have you done?

Comment 3 Patrick Tessier

2012-10-09 07:39:43 EDT

If I have no response I will close it.

Comment 4 David Rabely

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

2013-02-12 03:32:55 EST

I close the task.
