@ygbourhis No. So I deinstalled it, then downloaded from its website and activated it. Same results. Opera crashes if I click the gear icon in anything other than the Settings tab. Here's syslog:
 bryan: grep opera /var/log/syslog
Apr 10 12:50:30 Pentium90 kernel: [613766.044865] opera: segfault at a8 ip 0000000004f4fe65 sp 00007ffc00147540 error 4 in opera[1a1e000+5afe000]
Looks like there's a good probability that I have cruft in my environment (it's used for development after all). Be nice if someone could test in exactly Ubuntu 14.04.
