NSInvalidArgumentException: NSBundle(class) does not recognize loadGSMarkupNamed:owner:

[csanyipal]

Hi,

I develope a small application LPT_Interface.app with gnustep installed
on Gentoo Linux operating system. The installed packages are:

gnustep-base/gnustep-back-cairo Latest version installed: 0.18.0
gnustep-base/gnustep-base Latest version installed: 1.20.1
gnustep-base/gnustep-gui Latest version installed: 0.18.0
gnustep-base/gnustep-make Latest version installed: 2.4.0

When I try to run my app, I get error message:
NSInvalidArgumentException: NSBundle(class) does not recognize
loadGSMarkupNamed:owner:


I try to get some backtrace with commands as follows:

~/Programozas/Obj_C_ben/Emacs-szal/LPT_Interface/LPT_Interface.app $ gdb
./LPT_Interface

--------------------------

I didn't know whether the following warning cause this error?
warning: Can not parse XML syscalls information; XML support was\
 disabled at compile time.

I compiled gnustep-base with xml support, using USE="xml" flag.

Is this a bug, or not?
Any advices will be appreciated!
