[sylpheed:33265] Clipboard pasting messes up undo?

[Einar Lielmanis]

It seems that Sylpheed can lose the undo functionality when pasting the
data from clipboard into compose window, at least when pasting
with mouse;

to reproduce: 
1. have a text "test" in clipboard;
2. open a new compose window
3. type message text "aaaaa"
4. select with "ctrl-a"
5. mouse right-click, paste
   (text changed to "test")

observe that you can't get back to "aaaaa", undo does nothing. Pasting
with clipboard, ctrl-V, it seems to work ok (except for strange text
reformatting), but occassionally seemed to bug as well; I could not
reproduce it for certain though.

It seems to transition into state where deletes don't get saved into
undo buffer at all.

Running 64-bit arch linux with 3.0beta1, the problem was in stable as
well.

Cheers,
