Well, with the current SVN I can't open the theme panel on Ink. I get

That really is strange. Could you please place a break point on
__assert_fail() and see who is calling this. But before doing so, please
recompile back and Ink as well. Yesterday I had strange problem myself
that were caused by not recompiling back.
But in Gemas I can open the themes panel. And if I select Neos theme I get:

Thank you for adding this additional information. Is the path
'/home/german/GNUstep/Library/Themes/Neos.theme' the correct one, that
is the one you installed the Neo theme? If not please remove this path
and try again. GNUstep gui will only try to load the colour list as a
string after loading it with an archiver failed. So this is the original
problem here, hidden by an NSException that gets caught by the code.
As I wrote, I had problems myself yesterday and they all showed up in
NSUnarchiver not working. For some strange reasons this got fixed by
recompiling back.
As for the selector issue, this can only be explained by previous memory
corruption. Somebody needs to inspect this. Is it really that hard to
set a breakpoint and print out a few variables?

That is interesting, your selector string contains the additional
characters "Abnai\031". Where could these come from?
As I wrote I cannot reproduce it here and it will require somebody to
debug this who is actually seeing the problem. Could you please set a
breakpoint at line 180 in GSThemeInspector.m and start inspecting
stuff there?

Hi,
I can reproduce it too, the same way (previously I got other crashes,
but they are fixed now). I recompiled all of core. I did not reinstall
the themes, but Neos and Sleek are thematic only themes, they contain no
code.
I open the theme panel and select a theme. I will get a crash. To me it
looks like a buffer overrun when creating the signature or something
like that.

I was not aware of a bug in the theme panel. Could you please give the

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.
