2.5.2 -> 2.6.0 upgrade segfaults if certain packages are installed.
If a 2.5.2 install has zabbix-agent52 installed and tries to upgrade to 2.6.0 from console or GUI it will segfault.
Expected behavior: zabbix-agent52 doesn't seem to exist in 2.6.0 repo. Upgrader should recognize this and upgrade zabbix-agent52 to zabbix-agent54.
Actual behavior: Segfault
