Re: GNUstep Code Freeze

[Fred Kiefer]

I was not aware of a bug in the theme panel. Could you please give the 
details on how to reproduce it?

The back trace you report looks somewhat corrupted. The theme 
description ("Neos. The next step in theming, but with a strong root in 
NeXT.") is getting used as a selector name. This shouldn't happen in our 
code and it definitely doesn't happen on line 182 in GSThemeInspector.m. 
You will need to set a breakpoint a bit before that line to find out 
what actually goes on.

Before you do this, could you please make sure that you have recompiled 
all of GNUstep plus all the themes you have installed.
