GWorkspace ddbd dying when mdextractor connects

[Sebastian Reitenbach]

Hi,

having ddbd from GWorkspace running, then, when starting mdextractor, the 
latter tries to connect
to ddbd, but will die because of:
/usr/local/bin/mdextractor: Uncaught exception NSInvalidReceivePortException, 
reason: invalidated while awaiting reply

reason for this exception is, ddbd is dying.
With gdb connected to a running ddbd, I get this backtrace when it segfaults:

Program received signal SIGSEGV, Segmentation fault.

since its dying deep within gnustep-base, I'm a bit unsure whether this is a 
problem of the tools from
GWorkspace, or a more general problem in -base.

I'm on i386, OpenBSD 5.3-beta, with -base,make,gui,back,gworkspace from SVN.

thanks,
Sebastian
