Error: 'Error opening input stream (invalid filename?)' when calling method: [nsIObserver::observe] = NS_ERROR_XPC_JS_THREW_STRING
Source file: chrome://global/content/bindings/tree.xml
Line: 82

<http://lxr.mozilla.org/seamonkey/source/xpfe/global/resources/content/bindings/tree.xml#81>

This is the line that fails:
        !/Mac/.test(navigator.platform)

This doesn't affect Firefox because their version of tree.xml uses #ifdef/#endif in the preprocessor.

Currently filing under "XP Toolkit/Widgets: Trees" but possibly should be moved to the JavaScript Engine component.

That's a strange error. What does this code have to do with the observer service? Or streams? Are you that's the line that's throwing the exception?

What fun. As well as testing on a new profile, I've just installed a trunk build into a different location. Using this installation, I don't get the error.

comparing the two %Appdir%/chrome/ directories I seem to have a few extra .jar files in the problematic installation:

en-{mac|unix|win}.jar, US.jar, content-packs.jar. Looks like I'll need to do some housekeeping.

Marking this bug as invalid.

Just for reference: It was the greasemonkey.js in the components directory.
