Congratulations !
And still the moment for bug reports. :-/

Pikopixel doesn't seem to deal well with other themes on GNUstep, now 
that it has its own and overrides GNUstep defaults..

The theme changing dialog in the Info panel is now buggy : when I switch 
to the default GNUstep theme, Pikopixel sets its own theme, instead of 
the default one. Which is sensible but a little tough. But the real 
problem is that if I want to change again to another theme, all my 
themes are listed with the same name "Pikostep" in the Info panel and I 
can't change to another. I can only "revert to default theme", which 
sets my Rik theme as it is the default one.

Which is more annoying is an incompatibility with PikoPixel and the Rik. 
theme for me : it crashes at startup.

Since revision beta9a, Pikopixel segfaults on dry launch, right after 
that I push the OK button of the first dialog (creating an empty 
window). It doesn't occur when I open an image with it (using the 
context menu of GWorkspace).

I've launched it in GDB and got this backtrace :

There seems to be an incompatibility between the NSButton methods 
reimplemented in Rik and Pikopixel, right ?

Anyway, Pikpixel is still very impresssive and the new theme is very nice.
