You cannot reproduce it by just removing the local.groups file if you
already have an existing groupinfo file.

AFAICS, the problem occurs only if you have no local.groups file *and* 
no preexisting groupinfo file, which is the case on a real fresh 
installation.

In this case 'active' remains a NULL pointer after rereadactive() -> readactive()
and rereadactive() -> readlocalgroups(). Hence, mvactive(active) returns 
a NULL pointer as well and fetchnews finally aborts prematurely in 
mergeactive() -> findgroup() because 'oldactive' is NULL.  

I have appended a backtrace. Hope it helps.
