Comment #4 on issue 19116 by viettrungluu: Mac: DCHECK() failure in AutocompleteEditViewMac::OnWillBeginEditing() http://code.google.com/p/chromium/issues/detail?id=19116
I can trigger this, or a very similar, bug under completely different circumstances, with my CL-in-progress <http://codereview.chromium.org/164547>. Steps (with my CL): 1. Open a new chromium; should open up to NTP. 2. Cmd-O to open a tab-modal open sheet. 3. Cmd-T for a new tab. 4. Cmd-W to close the new tab. 5. Bam. Assertion failure and stacktrace below: [89305:267:208517200531541:FATAL:/Users/vtl/dev/google/chromium/src/chrome/browser/autocomplete /autocomplete_edit_view_mac.mm(619)] Check failed: [field_
