Segfault when closing application output tab

Seems to happen if
a) RunControl::stop() has been called (via Stop button in application output window) and
b) the stop mode is Asynchronous and
c) the tab is closed before the finished() signal is emitted.
Can be reproduced e.g. with the RemoteLinux run control, though you need to be quick with pressing the "force application to quit" button.
