Very occasionally (but replicably!) UFraw takes a Canon CRW image and produces a result in false colours. I am calling ufraw-batch from php\'s exec function, e.g.:
exec (\"ufraw-batch --wavelet-denoising-threshold=50 --wb=auto --out-type=jpg IMG_0001.CRW\");

It doesn\'t matter what the output type is, the result is always the same.

In the same environment DCRaw will convert the image without any errors.

    What camera model and UFRaw version are you using?

    Camera was a Canon SX120 pimped with CHDK; ufraw was the latest version:
    C:\Documents and Settings\Lee Traynor>ufraw-batch --version
    ufraw-batch 0.18
    EXIV2 0.21.1
    JPEG enabled.
    TIFF enabled.
    PNG enabled.
    FITS disabled.
    ZIP enabled.

    Please send me a raw file showing the problem. My email address is nkbj(at)users.sourceforge.net. Please use www.yousendit.com or a similar service.

    Update from private communication: The bug only happens when the --wavelet-denoising-threshold switch is present and ufraw-batch is called from a php script.

    Please try UFRaw 0.19.1 and report back.

    Very special case. I am closing this bug report due to no communication from the OR for a long time.
