I finally got the trace working. Made a little hack in the kernel
to do so (modified kern/kern_exec.c to not stop tracing on suid
processes).
The traces are quite long, I have looked through them and included
the parts where they start deviating.
On the 2.1.7 kernel:
283 dtmail RET stat -1 errno 2 No such file or directory
283 dtmail CALL stat(0xfa7e8,0xefbeb438)
283 dtmail NAMI "/usr/include/X11/bitmaps"
283 dtmail RET stat -1 errno 2 No such file or directory
283 dtmail CALL break(0x109fb0)
283 dtmail RET break 0
283 dtmail CALL break(0x109fb0)
283 dtmail RET break 0
283 dtmail CALL gettimeofday(0xefbfd080,0)
283 dtmail RET gettimeofday 0
283 dtmail CALL access(0x859451b,0x4)
283 dtmail NAMI "/etc/localtime"
283 dtmail RET access 0
283 dtmail CALL open(0x859451b,0,0x85bb060)
283 dtmail NAMI "/etc/localtime"
283 dtmail RET open 12/0xc
283 dtmail CALL read(0xc,0xefbfad38,0x1f08)
283 dtmail GIO fd 12 read 785 bytes

Continues....
With 2.2:
319 dtmail RET stat -1 errno 2 No such file or directory
319 dtmail CALL stat(0xfdf40,0xefbeb114)
319 dtmail NAMI "/usr/include/X11/bitmaps"
319 dtmail RET stat -1 errno 2 No such file or directory
319 dtmail CALL write(0x3,0xb76e0,0x47c)
319 dtmail GIO fd 3 wrote 1148 bytes

:
Pops up dialog box with error message.
I can't see from the trace why the 2.1.7 calls the break routine, what
is it anyway? I can't find it in my manpages.
What sort of trace should I do to help localise this problem
further?
