On the latest Lazarus revision under FPC 2.0.4, this problem
continues, but with a different reaction at first.
Please note that there is an attempt to touch memory that was not
allocated, or was released before it was needed to.
At first I do have response from the editor, but when I try to move
into the component palate, or object inspector, Lazarus crashes with
the following backtrace:

Same here. Only affects pasting to a TSynEdit from outside the
application. Here's a backtrace:
