  http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul|treeitem weight:
1 { -moz-binding: url("chrome://global/content/treeBindings.xml#treeitem") }

should be using:  style: 0x8813c70 {
  http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul|* weight: 0 {
display: 1[0x1]enum }
  http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul|* weight: 0 {

  http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul|treeitem weight:
1 { -moz-binding: url("chrome://global/content/treeBindings.xml#treeitem") }
}

To reproduce:

Edit->Preferences
Click on the arrow to close the "Appearance" subtree 

I get this with the bookmark manager and the dirviewer as well. At a guess, it
started happening sometime in the last 5-10 days or so.

ccing hyatt as the tree widget guy

Comment 2

[Pierre Saslawsky]

Another bug that I forgot to triage...
Reassigned to hyatt.

Comment 3

These days I also see this assertion w/ the bookmarking tree widget in the side
bar, which has also become quite slow with opening/closing of subtrees. Is this
slowness connected with the assertion?

Comment 4

[Boris Zbarsky [:bzbarsky]]

bbaetz, is this still an issue?  Prefs use an outliner now, not a tree, so they
certainly no longer show this bug... but there have been other changes that may
have fixed it too.

Comment 5

[j.j.]

Someone should close this without discussion.

Comment 6

[Michael Kohler [:mkohler]]

This is a mass change. Every comment has "assigned-to-new" in it.

I didn't look through the bugs, so I'm sorry if I change a bug which shouldn't be changed. But I guess these bugs are just bugs that were once assigned and people forgot to change the Status back when unassigning.
