Crash while computing minimum raw value of Canon Dual Pixel image

[Lawrence37]

Attempting to load a Canon Dual Pixel raw image results in a crash in dev.

This happens during the computation of the minimum raw value, which is used for raw de-haze. In this line, rawData is empty, so attempting to get the pixel value fails.

RawTherapee/rtengine/rawimagesource.cc

Line 8545 in 00360a6

m0 = rtengine::min(m0, rawData[row][col] - cb0);

I used an image obtained from raw.pixls.us. The web page is down, and I can't upload the image because I don't remember the license for this particular file.

I could provide some examples. Give the sun some time to settle, then i shoot 2..3 pictures.
//Edit:

No Crash on my end.
Compiled the latest git.
