Not really, as far as I know. You can tell strace to only show you certain calls, e.g. open, (see man page) but that would still show you it attempting to open files that don't exist. strace is by no means guaranteed to help you figure why something doesn't work. It's good for seeing exactly what happens, but you have to be able to make sense of the output. There's been times I've run something under strace and very quickly been able to diagnose the problem and times I've looked at the output of strace and found it of no help whatsoever. In the latter cases it may have been because I didn't really know what I was looking for and hence wasn't able to pick out relevant lines, or there was just nothing useful in there.
