Hi,
In version 0.21 found in Fedora 21, changing zoom level resets crop positions. This happens at every such change, 100% reproducible.
Steps to reproduce:
1. Open RAW (tested: Fuji SuperCCD RAF from S5600)
2. Switch to crop tab
3. Change crop area
4. Change zoom level
Expected effect: picture is zoomed accordingly, top/left/bottom/right crop extents do not change
Actual effect: picture is zoomed accordingly, top/left/bottom/right crop extents are reset to full picture
I suspect this is related to the previous bug where changing zoom level after 90deg rotation would mess with the uncropped picture dimensions (was Fedora 20). That bug isn't present in F21 though.
Problem persists with current cvs version.
The offending change (bisected):

Time permitting, I will try to create a fix.
