413785 - WARNING: NS_ENSURE_TRUE(aPresContext->Document()->GetWindow()) failed

Status: NEW

(Core :: DOM: Events, defect, P5)

Description

[Matthew Cline]

Attachment: C/C++ stack trace

I sometimes get the following error when using the debug build:

WARNING: NS_ENSURE_TRUE(aPresContext->Document()->GetWindow()) failed: file ../../../../content/events/src/nsIMEStateManager.cpp, line 176

The best way I've found to reproduce is to point Minefield at a locally stored minimal HTML file, use Ctrl-L to select the URL bar, press ENTER to load it, and immediately use Alt-TAB to switch to a non-Minefield window; not 100% effective every time, but three to four tries gets the warning 99% of the time.  The warning never shows up if the Minefield window keeps focus.

My machine is rather old, so whatever timing issue is involved might not be apparent on faster machines with the recipe I gave above.
