Bug 27097

Created attachment 32479 [details] Screenshot of Epiphany + Accerciser Steps to reproduce: 1. Launch Epiphany and Accerciser. 2. Perform a search in Google (e.g. 'webkit'). 3. In the search results page there should be an accessible of ROLE_TABLE. Locate it in the hierarchy in the tree of Accessibles (see attached screenshot). 4. Attempt to expand the accessible of ROLE_TABLE to see its children. Expected results: Epiphany wouldn't segfault Actual results: Epiphany segfaults (see below). I am using the current Epiphany and the current WebKit each from git and can reproduce this problem reliably. ~~~~~~ Program received signal SIGSEGV, Segmentation fault.
