Bug 26517 – webkit_web_back_forward_list_add_item() should add a ref for the history item

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Oliver Gerlich]

When using the pywebkitgtk bindings to manually add a WebKitWebHistoryItem to a back-forward-list using WebKitWebBackForwardList.add_item(), the caller currently has to keep a reference to the item because otherwise the item is destroyed. Example:

for uri in ["http://example.com/1/", "http://example.com/2/"]:
    item = WebHistoryItem(uri, "")
    bf_list.add_item(item)
backList = bf_list.get_back_list_with_limit(10)

This leads to a crash in the last line. Keeping the created WebHistoryItems referenced in Python (eg. by putting them into a global list) works around the problem. From what I understand, to fix this, add_item should add a reference to the item itself, so that the caller doesn't have to manually keep a reference.

This happens with webkit-gtk 1.1.9 and pywebkitgtk 1.1.5 and Python 2.6.2, on Ubuntu Jaunty (9.04).
