Description

Since darktable 2.2.0 the exposure module calculates wrong correction values for RAW files from some Canon cameras, e.g. http://www.rawsamples.ch/raws/canon/RAW_CANON_EOS_5DS.CR2 (see darktable-2.2.1-bad-exposure.png). With darktable 2.0.7 everything looks fine (darktable-2.0.7-good-exposure.png).
