Status: RESOLVED WORKSFORME

(SeaMonkey :: UI Design, defect)

Description

[Gérard Talbot]

I have seen this error  

Error: document.tooltipNode.target has no properties
Source File: chrome://navigator/content/nsBrowserStatusHandler.js Line: 281

reported in the Error console several times in the last 10 nightly trunk builds. I've searched for duplicates and couldn't find any (closest I found was bug 241125). I have a few old addons extensions installed. I don't know if these have an impact or are responsible for creating such error; for now, I don't think they have are involved.

Steps to reproduce:
Unidentified. Unknown for now.
I have not tried to use a fresh new profile.

Reproducible
Not always. Intermittent occurences.

Seamonkey 1.5a rv:1.9a5pre build 2007050408 under XP Pro SP2.

Setting initial state to UNCONFIRMED until I can find more solid info on this bug.

Here's the relevant block of code coming from
jar:resource:///chrome/comm.jar!/content/navigator/nsBrowserStatusHandler.js


   if (document.tooltipNode) {
     // Optimise for the common case
     if (aWebProgress.DOMWindow == content) {
       document.getElementById("aHTMLTooltip").hidePopup();
       document.tooltipNode = null;
     } else {
       for (var tooltipWindow =
              document.tooltipNode.target.ownerDocument.defaultView;
            tooltipWindow != tooltipWindow.parent;
            tooltipWindow = tooltipWindow.parent) {
         if (tooltipWindow == aWebProgress.DOMWindow) {
           document.getElementById("aHTMLTooltip").hidePopup();
           document.tooltipNode = null;
           break;
         }
       }
     }
   }

where
     document.tooltipNode.target.ownerDocument.defaultView;
is Line 281

I can not find more to support this bug. I'm going to resolve it as WORKSFORME.
