I have a bookmark whose URL is: file:///Bleeding%20Edge/Mozilla%20tree/src/mozilla/dist/viewer_debug/chrome/ global/content/default/commonDialog.xul This file no longer exists. But I now see in my bookmarks menu and popup and item "commonDialog.xul" that shows a folder listing for the Mozilla directory. My guess is the file channel code that treats "" like a directory listing is to blame here.
Fixed... switched some code over to use nsIFile instead of nsFileSpec.
