I worked with psi and it's crashed. I run psi again and connect to a server. Connection establishes successfully and psi crashes right away. In /var/log/messages i found: .... psi[21687]: segfault at 0 ip 685ec3 sp 7fff4d28c910 error 4 in psi[400000+4d2000] psi[21723]: segfault at 0 ip 685ec3 sp 7fff48bc02d0 error 4 in psi[400000+4d2000] .... It is reproducible from time to time. I tried to use mcabber with the same server. It works well.
