I deleteted .mozilla, and started from clean state after fixing the
libwallet.so issue.

I removed my .mailcap, created by OpenOffice 2.0 beta. I've left the base
.mailcap in /etc and /usr/pkg/etc which appear un-touched.

I still get MIME directed downloads going to the tempfile state in /tmp.

so I did ktruss on my program, and lsof. I appear to have some pipes/unix
sockets pointing back into itself (!) and I ktrace a loop of:

Is this some kind of 'not respecting eof()' bug on pipes used for IPC?
