Failed to read white balance information from NEF (D5500 RAW)
I don't have problem opening the NEF files from my D5500, but a particular RAW file from dpreview site threw the error message and couldn't be opened. Not sure if the file is corrupted or something with DT, submitting this bug report anyway in case it's something that needs to be worked on.
The offending file (ISO 6400 sample of D5500):
My darktable version is 2.5.0+333-g1f26b4f-dirty
Another file (ISO 6400 sample of D5600):
error message from the CLI:
[rawspeed] (DSC_0093.NEF) void rawspeed::HuffmanTable::setCodeValues(const rawspeed::Buffer&), line 176: Corrupt Huffman. Code value 92 is bigger than 16
[temperature] failed to read camera white balance information from `DSC_0093.NEF'!
Just saw your bug report and call for NEF lossy-after-split samples :-)
Let me know what I can do to help with testing. Thanks much.
