Now I hate gnus !

It's the second time that I opened gnus and all my nnml groups and all
my remote groups are no more subscribted !

This happened because my active file is almost empty:

$ cat Mail/active
x.zz_mairix-search-1 4277 4274 y

So does anybody know why this happened at all and how I can restore my
previous active file ?

I don't know if that helps but I saw this in my message buffer:

nnmairix-request-group: Wrong type argument: number-or-marker-p, x
\.zz_mairix-search-1

thanks for any help.
