gworkspace crashes on startup

[Sebastian Reitenbach]

Hi,

with gnustep core from svn, libobjc2 and gworkspace from svn, gworkspace 
segfaults for me on startup. This is the output I see on the console when 
starting:

$ GWorkspace

I don't know whether the missing semicolon is the cause of the fault?
How do I find out which plist it is parsing when it throws this warning, is 
there a default to enable debugging?

the stack trace of the core file looks like this, this is starting at stack 
frame 10637, but all the others before look the same, any hint how to see the 
last stackframes up to main()?
