601509 - Tabitem doesn't get removed when a tab is removed from tabstrip

Status: RESOLVED WORKSFORME

(Firefox Graveyard :: Panorama, defect, P2)

Description

[Rob Arnold [:robarnold]]

Every once in a while, I'll close a tab on the tab strip but it doesn't quite disappear. It seems to be kept alive in panorama except that I can neither close it there nor switch to it. Trying to switch to it gives no warnings, errors or other messages in the error console. It just zooms the image as if it were to switch and then resets the view as if I hadn't clicked it at all (except that the thumbnail is slightly moved or resized). Sometimes I can see an empty tab on the tabstrip (no content, just a slightly wider gap between tabs).

Seem to somehow have triggered some messages - these do not always occur!

TypeError: tab.linkedBrowser.currentURI is undefined = {message: 'tab.linkedBrowser.currentURI is undefined', fileName: 'chrome://browser/content/tabview.js', lineNumber: 4879, stack: 'TabItems__update([object XULElement])@chrome://browser/content/tabview.js:4879

This bug seems to be related to / caused by bug 585785 and bug 608589.

It seems that when a tab fails to close properly, it always leaves a remnant in the tab bar (the slightly wider gap, described in comment 0).
Additionally, it sometimes (but not always) leaves a non-functional tabitem in TabCandy.

Rob, Andreas, I'm unable to reproduce this bug. If STR which consistently produces this, or even a screen capture, could be provided, that would be helpful.

I can't reproduce the bug anymore.
