Hi, I can't really follow the mailing list so some of these might already known and fixed. I just tried to install a gemtools client from universe. I'm using the latest pharo-dev. Installing FFI brought up an syntax error because there is an attempt writing to a temp. Did this change with the closures? I think this is fixed by the version some can load via the ScriptLoader. Next I encountered a problem with MIMEDocument. I think it is Issue-631. There is an incorrect usage of the MIMEDocument interface. I changed it but wanted to store it in PharoInbox but my image crashes if I try to. It is: Segmentation fault -1178673304 UUID>initialize -1178673420 Behavior>new: -1178673512 >new I updated my vm to exupery-0.15.1 but still has the same behaviour. I attached a patch for the MIMEDocument issue on Issue-631. Than I met InputSensor. InputSensor default returns an instance of InputEventSensor. This looks just strange to me. Is this right? Norbert
