not fully NetBSD-related: i have a problem and no idea to solve

first - system(s) configuration:

1) host machine running NetBSD, or FreeBSD or linux (no matter, same 
effects) with GNOME version 2.<=10 (all version give same effects), 
running gdm for remote displays. no X local display.

2) X-terminals which are super-cut version of NetBSD 1.5.3+statically 
compiled X server that runs with -query to host machine 1). No fonts, 
uses font server on 1) too.


such configuration works perfect if i use fvwm2 and icewm.

it works perfect too if after using fvwm2 or icewm i will log out and THEN 
log on into gnome desktop.

BUT - if i log on into gnome desktop at first time (after X server 
started) it crashes after a short while - before displaying any progress, 
or quickly after displaying gnome startup window.

X crashes without first putting anything to it's log.


problem is at first login after X server start, NOT X terminal's 
NetBSD start. if i would press CTRL-ALT-Backspace so X server will exit 
and (by script on terminal) restart, it works as first start.


could anyone help me how to find a problem at all. i just have no idea 
where to search!


after this: my X terminals have no problem handling any apps, with and 
without gnome.
