[Message part 1 (text/plain, inline)]

 Apologies for the noise. I have found out that this problem is  
related to "metered connections". On those ones, Emacs cannot trigger  
opening of the file and is not capable of returning the right error  
message. Once I disable the option "metered connection" from the  
network, Emacs operates as expected. I suspect this cannot really be  
attributed to Emacs, except for the lack of error message in the first  
situation.
