Can you give me some hint, what can be the cause of the problem?

after which the debugger (I use mono-debug) quits. The above happens =
whenever I try to select any option from the menu.

My configuration:

RedHat Linux 9/x86 with some updates (via apt-get)
Relevant package versions:

gtk2-2.2.1-4
pango-1.2.1-3
atk-1.2.0-2
glib-1.2.10-10
gtk2-devel-2.2.1-4
pango-devel-1.2.1-3
atk-devel-1.2.0-2
glib-devel-1.2.10-10
glade-0.6.4-9
libglade-devel-0.17-11
libglade-0.17-11
GConf2-2.2.0-1
GConf2-devel-2.2.0-1

mono,mcs,gtk-sharp and debugger compiled from anonymous CVS.
Cygwin/XFree86 running on Windows XP/Professional. Other gtk =
applications (like gedit) work flawlessly with this X-Server.

Because of this problem I've never been able to run debugger =
successfully and I really want to try it.
