[sylpheed:30953] nobody noticed the (included) editor's undo bug ?

[Cristian Secară]

It's been long time I observed a very annoying bug, but strange that
nobody appears to observe that.
If I delete something and then undo, the text will almost never come
back as it was before, either random characters, or random words, or
random parts of words, or other bizarre things will appear. After
several undo/redo cycles, the original text is completely gone.

Hm ?
