Henrik,

You pointed me in right direction by suggesting the history log file. 
In there it complained that it could not open allevents.  I found that 
the allevents file had its ownership changed from hobbit to root.  Fixed 
that and no more segfaults.

I don't know how the ownership changed, but I'll find out; flogging will 
commence shortly :)

Thanks very much.
