#405 ufraw-batch requires .ufrawrc to exist
Depending slightly on the invocation, ufraw-batch crashes, segfaults, or goes into a tight loop if it is run from an account that doesn't have a valid .ufrawrc file. Here is some typical failure output, using a CRW file from /tmp:
bash-4.2$ convert '/tmp/P2007.04.12-19.49.56-2285.crw' jpg:- >/dev/null
convert: FailedToExecuteCommand "ufraw-batch" --silent --create-id=also --out-type=png --out-depth=16 "--output=/tmp/magick-18075wv7ThMuvwp03.png" "/tmp/P2007.04.12-19.49.56-2285.crw"' (-1) @ error/delegate.c/ExternalDelegateCommand/483.
convert: delegate failed"ufraw-batch" --silent --create-id=also --out-type=png --out-depth=16 "--output=%u.png" "%i"' @ error/delegate.c/InvokeDelegate/1333.
convert: unable to open image /tmp/magick-18075wv7ThMuvwp03.ppm': No such file or directory @ error/blob.c/OpenBlob/2702.
convert: no images definedjpg:-' @ error/convert.c/ConvertImageCommand/3252.
The above failure happens about 90% of the time; the remainder of the time produces a CPU loop. If I capture the invocation parameters and run just ufraw-batch from the command line, I get either a CPU loop (higher probability) or a segfault. The invocation in this case is:
ufraw-batch --silent --create-id=also --out-type=png --out-depth=16 --output=/tmp/magick-749FI13yEEayofD.png /tmp/P2007.04.12-19.49.56-2285.crw
Copying in a valid .ufrawrc from another account cures the problem.
In case it's relevant, here's the EXIF from the picture I tested with, slightly edited to anonymize certain data:
