Wrong size when open CDR files

[Mitko]

I was using Inkscape when noticed that there is some scaling when opening CDR files. In fact the measures I've got from the CDR file format are wrong. Attached the file.
Unfortunately, I cut some metal profiles before noting that the sizes are wrong.

confirmed on Windows 10, Inkscape 0.92.1 r15371

I do not have access to CorelDraw, so I used ExifTool 10.31. According to exiftool the page size is 600x600 mm.

According to Inkscape the page size is 1700.7874 px wide, which is equal to 450 mm, if you assume an internal resolution of 96 dpi in Inkscape.

The size of the document is determined by libcdr [1].

libcdr returns a width/height of 1700.7874 px, so if that value is wrong this is an upstream bug (see [2]).

fwiw, if you interpret the 1700.7874 as pt rather than px, then you get the right size.
i.e. perhaps Inkscape needs to do an internal conversion from pt to px similar to what is normally done for pdf files
