I'm having the same problem on an Intrepid upgrade from 8.4. When clicking the one of the 3 app launcher buttons (web browser, mail, help) on screen1, gnome-panel becomes unresponsive on both screens, consumes 100% CPU, and opens a blank error dialog that I can't close.
Interestingly, I have X configured with 2 screens using Nvidia drivers (1 session, no Xinerama), and this problem only happens when clicking on the launchers on screen1. The launcher buttons on screen0 behave properly. And as stated by Fabián above, apps start normally when using the menus on either screen. I've attached a stacktrace from when gnome-panel is stuck / using 100% CPU. ** Attachment added: "gnome-panel.trace" http://launchpadlibrarian.net/19203173/gnome-panel.trace -- Intrepid: gnome-panel eats 100% CPU when apps launched from panel launchers, blocks https://bugs.launchpad.net/bugs/291656 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
