I tried to upgrade to v1.2a from 1.0a after exporting
installing v1.2a, importing the database, and then
spamprobe -P 100 spam Mail/spamprobe
but it dies like so:
~ % spamprobe -P 100 spam Mail/spamprobe
caught signal 11: quitting
system is Fedora Core 2, fully updated. Have been running
1.0a trouble free since shortly after it was released.
