Description:

The new Darktable version 2:2.2.2-1 yields a segfault after some ttime when working with a RAW file. I have experienced this problem with DNG files from a Pentax K20D. First there is a message that this camera could not be found in the database. But the version 2:2.2.1-1 did not complain so. When opening a RAW (DNG) file, the applicaton crashes within some time, sometimes even when no further action have been made.


Steps to reproduce:

have been wirtten before.

Here is a terminal protocol:

[defaults] found a 64-bit system with 16321280 kb ram and 8 cores (0 atom based)
[defaults] setting high quality defaults

(darktable:17394): Gtk-WARNING **: Failed to measure available space: Der angegebene Ort wird nicht unterstützt
RawSpeed:Unable to find camera in database: 'PENTAX' 'PENTAX K20D' 'dng'
