Hi!
I'm running sage 5.11 on linux. I have a file called misc.sage which %attach seems to not like very much. The problem seems to be the filename, since even an empty file or just a print statement in it produce the same reaction. Is this a bug? Is this present in 5.12 too?
sage: %attach misc.sage [2/708]
