msieczka,
I cannot seem to reproduce this Ubuntu with the 0.11.0 branch.
Would you be able to provide an example dataset that you are having trouble with?
Sample indexed pallette png attached. Steps ro reproduce:
- Start georeferencer plugin.
- Load the attached topo.png.
- Select Helmert transformation.
- Set the minimum 2 points as required.
- Apply transformation.
In a result a new raster is created. It should be have the same colortable as the input had, but it's greyscale instead.
BTW I noticed 3 more issues with the georeferncer:
- In the compression dialog all 3 methods are marked "unstable". Does this warning still hold true. Could you please remove it if not?
- The "Arrange plugin windows" could do it's job better - currently it makes the file selector overlap the main georefencer window, at least on my Debian testing with Gnome.
- The main georeferncer window is badly missing the minimise and maximise buttons. The file selector could use the minimise button as well.

Dialogs don't have minimize buttons, but the new auto arrange should help.
msieczka,

Also can you clarify where Georeferencer is forcing the greyscale, is it in the georeferencer window or one you are back in the main QGIS canvas?
