Hello Stephane,
SS> Is this a know issue ? Where is the place to report bugs (or check if SS> some have already been raised) ?
can't help with the issue but:
Mantis is the place to report and view bugs but this list maybe better squeak-dev should get an announcement of the bug entered.
Mantis has a help which I read every time I report a bug, so I know the proper category. Mantis is at: http://bugs.impara.de/
Cheers,
