Same here when running gnome-system-monitor with iPhone 3 connected via USB.
Some observations: 1. As noted by other posters, I get tons of output from "dbus-monitor --session" 2. As mentioned above, when starting gnome-system-monitor, at first the only output on the command-line is: "** (gnome-system-monitor:6765): WARNING **: SELinux was found but is not enabled." 3. While experiencing the problem, the command-line that I started gnome-system-monitor from received these two messages thousands of times: (gnome-system-monitor:6582): GVFS-RemoteVolumeMonitor-WARNING **: cannot add match rule 'type='signal',interface='org.gtk.Private.RemoteVolumeMonitor',sender='org.gtk.Private.GPhoto2VolumeMonitor',': org.freedesktop.DBus.Error.LimitsExceeded: Connection ":1.236" is not allowed to add more match rules (increase limits in configuration file if required) (gnome-system-monitor:6582): GVFS-RemoteVolumeMonitor-WARNING **: cannot add match rule 'type='signal',interface='org.freedesktop.DBus',member='NameOwnerChanged',arg0='org.gtk.Private.GPhoto2VolumeMonitor'': org.freedesktop.DBus.Error.LimitsExceeded: Connection ":1.236" is not allowed to add more match rules (increase limits in configuration file if required) 4. Usually, after I plug in my iPhone, my system automatically mounts both "Max's iPhone" and "Documents on Max's iPhone". However, when I unplugged the iPhone, restart gnome-system-monitor, and plug the phone back in, only the main device is auto-mounted, not "Documents". 5. After removing and replugging the phone, I was not able to reproduce the problem during that login session. It only happened if the phone was already plugged in before I logged in. I'm using Ubuntu 11.04. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-system-monitor in Ubuntu. https://bugs.launchpad.net/bugs/441828 Title: System Monitor ignores close request and uses 100% of one core -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
