gnat-gps 2.1.0-3 (debian) crashes the whole X-Windows system

Hi there,
whenever I try to compile a simple "Hello world" programm with gnat-gps
2.1.0-3 from the debian unstable tree it crashes my whole X-Windows
system, killing the display manager and taking every running program
with it down the drain... I have no clue how to track this down, because
there is no usefull debug information except the log file from gps (see
attachment). Maybe I should compile it from the source, but I would like
to use the debian packages. I even compiled gps from the debian
source-package, but as soon as I hit the F4 key, I have to log in again.

Regards Helge.
