I can reproduce, the plugin tries to connect unsuccessfully to the unix socket for a few seconds, and the crashes.

firefox by default will kill the plugin after 45s of hanging.
By default, the xpi plugin will take up to 55s... we can lower this to 10s imho, with 1 tries every 10s.. With this change, it no longer crashes.

Secondly, if the pipe is already connected, connect() returns -1 with EISCONN errno.
