[Bug 254943] [NEW] screen's 'power detach' (ctrl+a DD) causes Warning: Program '/bin/bash' crashed error, and bash does indeed crash

I think the summary tells the whole story, this does not happen in any
other X terminal emulator, so I am sure it is konsole-kde4 and not
screen. To recreate this bug, open a kde4 konsole run screen, then apply
the key combination ctrl+a DD (this invokes screen's power detach
function) and the error will appear, the tab is then useless. However
the screen session does successfully detach so there is no data loss,
even within bash sub-shells, i.e. running bash within bash and starting
screen on that shell.

This only affects bash; zsh,csh and ksh all function correctly on a
power detach.
