Cartographic composer: scale and rotation options do not work for north arrow

[veroandreo]

When I try to add a North Arrow in the Cartographic composer, if I accept all settings by default and click OK, it works, but I get a huge north arrow.

If I then try to scale or rotate the north arrow, the apply button does not produce any visible effect and the OK button does not close the dialog, only the "x" in the corner does, and afterwards the grey box representing the north arrow disappears. Then, the arrow appears in the preview, but I do not have control over it.

I attach screenshots.

draft mode in g.gui.psmap, after north arrow has disappeared

preview mode in g.gui.psmap, north arrow appears (not shrunk as expected)

I can't reproduce. Maybe could you list your steps exactly how you do it?

[annakrat]

Also does it work in 76?

[veroandreo]

Replying to annakrat:

I can't reproduce. Maybe could you list your steps exactly how you do it?

1. Open Cartographic composer from GUI (File--> Cartographic composer)
2. Add map frame and select elevation raster map
3. Add north arrow, select n_arrow1_fancy.eps, click OK
4. Double click over north arrow in map
5. 2 or 3 clicks over minus in Scale, Click Apply <<-- nothing
6. Click OK <<-- nothing
7. Close "North Arrow Setting" box with the x in the corner
8. North arrow becomes invisible
9. Generate preview and north arrow is there (original position and size)

I still can't reproduce. Isn't there any error in Layer manager console?

Yes, here it is:

I think it is because I click over minus more than 3 or 4 times and then north arrow becomes very small... The problem is I only see minus or plus sign, I do not know how much I reduce the size or rotate (see attachment, is this the same for others or only in fedora?).
