Bug ID: 41733
           Summary: wineconsole: crashes in emacs mode when pasting
                    (Ctrl+Y) empty buffer
           Product: Wine

Backtrace of crash.

Originally reported as https://bugs.debian.org/844412.

wineconsole in emacs mode crashes when pressing "Ctrl" + "y" (paste buffer)
while the buffer is still empty.

This is reproducible if wineconsole is in emacs mode (changing to emacs mode
requires restart, see bug #41732).

In a fresh wineprefix:

$ wineconsole
Right-click -> Set defaults
Setup - Default settings -> Configuration
-> Choose Edition: Emacs
-> Restart wineconsole
-> "Ctrl" + "y"
-> Crash, see backtrace.txt.
wine: Unhandled page fault on read access to 0x00000000 at address 0x7b43a074
(thread 0059), starting debugger...

Once I copy something to the buffer it works as expected:
$ wineconsole
Z:\home\jens>foo
-> "Strg" + "w" cuts "foo"
-> "Strg" + "y" pastes "foo" as expected.
