Happening to me too. It seems to be happening since the latest update round, although gnome-system-monitor wasn't updated then. The version of gnome-system-monitor I have installed is 2.28.0-0ubuntu1.
On my system too it does not happen all the time. The first time I tried running it with strace it did work, for instance. But it happens more often than not. Since the application is not crashing I don't think backtraces are applicable. I have attached an strace log. I captured it with the following command line: strace -Ff -tt gnome-system-monitor 2> strace-gnome-system-monitor.log I then clicked once on the close button in the title bar (which did nothing), and then ended the program by pressing Ctrl+C on the console. ** Changed in: gnome-system-monitor (Ubuntu) Status: Incomplete => New ** Attachment added: "strace output" http://launchpadlibrarian.net/39364904/strace-gnome-system-monitor.log.bz2 -- System Monitor won't close through normal methods, I have to kill the process. https://bugs.launchpad.net/bugs/482680 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
