Comment (by davidsarah):

 Replying to [comment:2 T_X]:
 > Ah wait, just found what's different: I'm copying _from_ tahoe-lafs _to_
 a local directory. You're doing it the other way around and there I also
 get that "lost connection". However when copying from tahoe-lafs, there I
 don't get it: [...]

 To avoid confusing other readers, you meant "when copying to tahoe-lafs,
 there I don't get [the error]".

 Anyway, it turns out that {{{scp}}} was just expecting the server to write
 the error message. (I still think that's a bug, but never mind.)

 With attachment:fix-1442-and-1446-version2.darcs.patch, we get:
 {{{

 davidsarah at 127.0.0.1's password:

 than 'df'.
