Bug reproduced with strace-ing. The problem seems to be that it sends a SIGINT to the init process (pid 0): See the end of the attached strace log:
8587 kill(0, SIGINT) You can try it yourself by simply running qtoctave and pressing the 'X' button _several_ times. I'm not a QT whiz, but maybe you should read this: http://doc.trolltech.com/3.3/qprocess.html#kill (Instead of calling the 'kill' system call directly) and this: http://doc.trolltech.com/3.3/qprocess.html#isRunning My guess is that QTOctave is trying to kill the connection process after it has been killed. ** Attachment added: "qtoctave_strace.log.gz" http://launchpadlibrarian.net/16739492/qtoctave_strace.log.gz -- QtOctave "Stop process" button killed Xorg https://bugs.launchpad.net/bugs/251133 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
