Status: NEW

(Core :: Layout, defect)

Description

[Christian Persch (GNOME) (away; not receiving bug mail)]

firefox trunk debug build from 2005-06-13:

Steps to reproduce:
0) Load the testcase
1) Click the "Test case for bug 116256" link
2) In the popup window, focus the location entry

Now the window closes, and I get this on terminal:

Still around in 2008-01-18 trunk from closing a http://tvtropes.org/ tab, though the stack trace is somewhat different:
