crab getoutput mixes up wrong options for copy command

Something maybe due to "thread confusion" ?
See following[1] fragment of crab.log, some copy command have the correct `-t ` while all of a sudden one queue command has `--srm-timeout ` which is the one for lcg-copy.
This makes no sense from the code, there is no indication that the option could be different from one file to the next one.

The hypothesis of thread confusion is also because earlier in the log I find [2]
