enterMode BR: range.pasteHTML and "Invalid argument" errors

[Wiktor Walc]

The attached sample can be used to trigger "Invalid argument" errors in CKEditor.

Bug 1

Invalid argument. selection/plugin.js line 775

• Press "Select All" or Ctrl + A
• Press "Insert Span" button

Bug 2

Invalid argument. core/dom/node.js line 240

• Select word "This" (using arrow keys, to make sure that surrounding white characters are not selected)
• Press "Insert Span" button

True for Webkit, Gecko and Opera from CKEditor version 3.0. No errors are thrown in IE.

Messages from DOM inspectors:
Dragonfly: Cannot convert 'oEditor.document.$.selection' to object
Firebug: oEditor.document.$.selection is undefined
Chrome: Uncaught TypeError: Cannot call method 'createRange' of undefined
Safari: TypeError: Result of expression 'oEditor.document.$.selection' [undefined] is not an object.

Still reproducible in 3.6.2, I'm attaching a few screenshots of both issues that can be reproduced using attached pasteHTML.html sample.

Case 1 investigation with debug: screenshots 1_1-1_4 and 2_1-2_3 (This error happens in selection/plugin.js, method getBoundaryInformation(). The child node doesn’t have a valid nodeValue)

Case 2 investigation with debug: screenshots 3_1-3_3

Screenshots and description were provided by original reporter, cc-ed to this ticket.

Both TCs are not reproducible on IEs. And they never were on other browsers because this code uses IE specific API, so it always fails.
