[Evolution] Email composer butchering messages erratically

[Jonathan Ryshpan <jonrysh pacbell net>]

Problems:

1. When deleting replied-to text, more text is deleted than highlighted, generally all of the text marked replied-to.
2. The cursor jumps unbidden to the end of the message.  This happens most often while deleting highlighted text, but occasionally for no apparent reason, when either entering or deleting text.
3. Lines marked as part of a reply, though otherwise empty,  can't be deleted.
4. Fonts also change for no apparent reason.

All these happen erratically, especially 2, which makes it hard to provide examples, but I will attempt it if desired.
