In general, and here in particular, it would be useful if you can give 
more information than "This keeps failing". There probably is an error 
message, or does it just fail without a message?
Grant Edwards' guess about brace expansion was valid, but it seems it 
was not the cause for this problem, although it would have been a cause 
if you had indeed used the command you showed as an example. That leads 
to another advice, if you simplify the failing command, which is a good 
idea, you should verify that the problem is still the same.

Also, you should not top post to a mailing list.

Regarding your problem, you should use strace to see what happens.
