problem z apt i testing

[Blazej <narm@tlen.pl>]

Mam problem z apt : zawsze kiedy dodam do sources.list jakis adres (tak samo 
na icm'ie jak na ftp.pl.debian.org) z katalogiem testing, to wyskakuje mi 
mniej wiecej taki blad :
Reading Package Lists... Error!
E: Dynamic MMap ran out of room
E: Dynamic MMap ran out of room
E: Dynamic MMap ran out of room
E: Error occured while processing webmin-webalizer (NewVersion1)
E: Problem with MergeList 
/var/lib/apt/lists/ftp.icm.edu.pl_pub_linux_debian_dists_testing_main_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.
Kiedy zmienie testing na stable wszystko dziala. Jestem dosc zielony w tej 
materi. Z gory dzieki za pomoc.
