Hi Andreas,
the problem comes from Monticello 1.5 which is AFAIK now used in squeak-dev image. (Note that the squeak-dev image from Damien for 3.10 is still beta!).
So let's try the real 3.10 without anything loaded. The offical release 3.10 image is http://ftp.squeak.org/3.10/Squeak3.10.gamma.7159.zip
When I use this clean image and open Universe Browser, select "update list from network", then load System ->FFI Version 3.9.1 -> IT WORKS AND LOADS FINE
(but still has the NetNameResolver problem (Mantis 6980) we discussed in March and which requires your patch for the image before loading FFI)
Using Monticello 1.5 in Sq 3.10 is currently problematic. For instance it makes an ugly overrides for HTTPSocket>>httpPut:to:user:passwd: where HTTPProxyServer class variable is used directly instead of using "self httpProxyServer". This was OK for pre 3.10 but now things have changed.
Bye Torsten
