LibreOffice 5.0.0, Ubuntu 12.04

The bug can be reproduced by these steps :

1. lauch writer
2. select Extras - Options - LibreOffice - Colors
3. in the dialog the color palette of standard.soc is shown
4. select the button to load a palette file and load any different palette
5. the dialog presents the new palette just loaded
6. click OK, the dialog disappears

7a. select Extras - Options - LibreOffice - Colors again, the dialog shows the
old palette from standard.soc, not the palette just loaded

or
7b. Select any piece of text
8. try to format the background color of the selected text
9. the dialog with the format settings appears
10. select the tab to change the background color
11. the dialog with the color palette appears but the colors shown are from the primary standard.soc, not from the color palette loaded and assigned by clicking OK in step 6.

After loading a new palette the OK button of the dialog does not act as expected. The new palette is not assigned for use, but is discarded instead.
