this throws a lot in browser-chrome tests.
see bug 481406 for more informations.

Comment 3

[:Gavin Sharp [email: [e-mail]]]

I don't see why this would be happening after a quick look through http://mxr.mozilla.org/mozilla-central/search?string=browser-search-engine-modified . All of the observer objects seem to be valid.

Comment 4

[:Gavin Sharp [email: [e-mail]]]

Oh, actually, I guess this could be caused by the search bar adding itself as an observer and then having its XBL binding destroyed without being removed (IIRC XBL destructors aren't always called). I suppose this could also be causing leaks...

These two seem to be related: bug # 83635 and bug # 230086.

mochitest-browser-chrome: (3 platforms)

Firefox 3.5:
no bug.

Firefox 3.6:
Multiple tests, like
{
TEST-INFO | chrome://mochikit/content/browser/browser/base/content/test/browser_overflowScroll.js | Console message: [JavaScript Error: "[Exception... "'JavaScript component does not have a method named: "observe"' when calling method: [nsIObserver::observe]"  nsresult: "0x80570030 (NS_ERROR_XPC_JSOBJECT_HAS_NO_FUNCTION_NAMED)"  location: "JS frame :: file:///builds/moz2_slave/mozilla-central-linux-unittest-everythingelse/build/firefox/components/nsSearchService.js :: notifyAction :: line 664"  data: no]" {file: "file:///builds/moz2_slave/mozilla-central-linux-unittest-everythingelse/build/firefox/components/nsSearchService.js" line: 664}]
}
NB: Some tests are not related to "Search".

SeaMonkey 2.0:
Various xpinstall tests, like
{
TEST-INFO | chrome://mochikit/content/browser/xpinstall/tests/browser_cookies.js | Console message: [JavaScript Error: "[Exception... "'JavaScript component does not have a method named: "observe"' when calling method: [nsIObserver::observe]"  nsresult: "0x80570030 (NS_ERROR_XPC_JSOBJECT_HAS_NO_FUNCTION_NAMED)"  location: "JS frame :: chrome://mochikit/content/browser/xpinstall/tests/browser_cookies.js :: test :: line 17"  data: no]" {file: "chrome://mochikit/content/browser/xpinstall/tests/browser_cookies.js" line: 17}]
}

SeaMonkey 2.1:
"Same" as SM 2.0 plus more xpinstall tests.

Can I morph this bug to Core, or should I file a separate meta bug.?.

I don't see this with the STR in comment 0, and it's also not in browser-chrome logs anymore AFAICT.
