Repeatable X11-crash

Hello!

I'm running a -current snapshot from 27th.
OpenBSD werkel.rechners.lemarit.com 3.8 GENERIC#459 i386

I'm using fvwm that comes with the snapshots.
Whenever i try to run a java-app that wants to open a window, X crashes.

alf@werkel:11$ tail  /var/log/Xorg.0.log.old                          
Fatal server error:
Caught signal 11.  Server aborting


Please consult the The X.Org Foundation support 
         at http://wiki.X.Org
 for help. 
Please also check the log file at "/var/log/Xorg.0.log" for additional information.

My java port is quiet old, it dates from Aug. 2, so port and system are
somewhat out of sync, but i don't think that this should allow java to crash
the X-server.
This started just a week ago, i'm running snapshots more or less regular.
Can someone reproduce this?
