thanks for the report!
Can you open a bug entry and a test (it would be lovely).

BTW andrei I think that we forgot to book an hotel for your visit :)
Can you tell me again when you are coming that we try to fix this little point :)

Hi,

This code fails in both Pharo 2 and Pharo 3: 'FileSystem disk root children sorted'
It throws this exception: FileReference(Object)>>doesNotUnderstand: #other
