Segfault at trying to run a Virtual Machine

[Enhy]

I'm using a Debian system (Lenny version) with the x86_64 based kernel 2.6.22-3-amd64. I've installed VirtualBox 1.5.4 and all seems to run fine until I try to open a Virtual Machine, then I get a flash and the status showed under the VM name change to "Aborted". The system is not installed yet. Locking the /var/log/messages file, I get the next:

Jan 19 14:58:00 Aragorn kernel: vboxdrv: Trying to deactivate the NMI watchdog permanently...
Jan 19 14:58:00 Aragorn kernel: vboxdrv: Successfully done.
Jan 19 14:58:00 Aragorn kernel: vboxdrv: Successfully loaded version 1.5.4 (interface 0x00050002).
Jan 19 15:06:44 Aragorn kernel: VirtualBox[6577]: segfault at 0000000000000028 rip 00002b64dd0d16ee rsp 00007fffcdf69d90 error 4

Curiosly, if I run VirtualBox as root, it works right, but the other user is member of "vboxusers" group.

Any idea to solve the problem? Thank you Enhy

Does this problem still persists? If so, please could you try to generate a core dump? See ​http://www.virtualbox.org/wiki/Core_dump

Please retry with 1.6.0 and reopen if the problem still persists.
