Avast go down with error:
avastgui[2386]: segfault at 682e39b6 ip 00413a84 sp b2c1314c error 6 in libc-2.10.1.so[3a1000+13e000]
Will have look at it, probably tommorow. But, running it under strace -f will produce more useful output for us (together with the full comandline, used - probably also with a file that caused this).
regards,
