Machine type (via `uname -a'):

Linux konata-chan 3.2.0-37-generic #58-Ubuntu SMP Thu Jan 24 15:28:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Steps to reproduce:
1) With a valid application or test harness incorporating libraw, attempt to decode an .s rw into a JPEG and save the result to disk.

Notice that a 'stray' file containing the name of the saved image and the process id is left behind in the directory where the conversion took place.

(Sample .srw files that exhibit the behaviour may be found at http://www.photographyblog.com/reviews/samsung_nx1000_review/sample_images/ )
