Comment #6 by Gianluigi GRADASCHI:

Hi Benoit,

it just happened with the last master as well, I tried to open a program in another window of the IDE and nothing happened, so I gave the commands you suggested yesterday assuming that the most recent process is the one that is blocked:

gian at gian:~$ pidof gbr3
157291 157130
gian at gian:~$ sudo gdb gbr3 157291

To be on the safe side, I debugged the other program as well:

Unfortunately I understand little about Gnome Debug, tell me if I get the commands wrong and ask for more tests.

If I am able to do them, gladly do so
