Preference panel: side bar width not correctly displayed
Desktop: Kde 4
The preference panel does not show the current value of the side panel width. It only shows 300. However, the size of the panel is correct (but not 300).
How to reproduce:
1. Start Darktable
2. Go in the preference panel
3. Change the value of "width of the side panels in pixels" to 600
4. Restart Darktable
5. See that the panels are of the right size
6. Check the value in the preference panel (you will see 300).
At step 6., we should see the actual value (600 here).
