[mythtv] seg fault - exit code 139?

[mythtv at ripnet.co.uk]

Hi,
Just built the new CVS for today, and am getting a seg fault after "Seem to be woken up by USER" on the backend.
The exit code is 139.
Any clues as to what it is? im running dual WinTVNova-T's on Mandrake10. Was working fine before I built the new CVS
(although, of course, i noticed JUST after I removed my backup of my old 'stable' CVS version from a month or so ago)
cheers
