Hmm. I've preivously been told not to use "Failed to" but instead use
"Could not"... Didn't notice that Tom used the other one in his
suggestion.

Tom (or someone else) - can you comment on if I misunderstood that
recommendation earlier, or if it still holds? I'll hold back a commit
until someone has commented on it :-)

Also, from this patch, you removed the %m part - I have re-added that
before commit.

(I will not for now comment on the rest of the mail, I'll leave that to
Tom)
