Subject: [PATCH] gui-wizard-gtk: wizard: Fix invalid memory read
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This partially reverts 7aba6e53bbfeedaacd95bbaa5e0c5e325a3e6a8d, which
results in “event” being inappropriately freed before a “goto” statement
is executed and the value stored in “g_event_selected” is read.
