Description Brian Holt 2013-07-04 01:46:37 PDT
+++ This bug was initially created as a clone of Bug #118362 +++

When I reported this originally I did so thinking that both bugs could be fixed in the same file fairly easily.

However the leak below in AccessibilityUIElement::title calls webkitAccessibleGetName(AtkObject*) that sometimes returns a char* that is created by g_strdup but it also sometimes returns a value stored in a cache.  Freeing that would be a disaster.  

This is probably not worth the effort required to refactor to fix the few bytes leaking, but opening this bug to track it anyway.
