D12567: Avoid octave backend crushing, when we try to kill ended process

[Alexander Semke]

asemke added a comment.


  Shouldn't this check if(m_process->state() != QProcess::NotRunning) be done in a central place so that this logic applies for all backends? It shoudln't be possible to call the interrupt action in worksheet or in cantor_shell/part at all if the process is not running. But we can maybe also safe-guard this in all the *session.cpp files.
  
  calling quit() in an octave session results in a permanent "Calculating..." message in the status bar. Clicking on the interrupt crashes cantor. This problem is a bit similar to https://bugs.kde.org/show_bug.cgi?id=372075.
