Well, this was pretty hard to get working because of the dependencies on newer stuff, and I ended up ignoring them whenever I could get away with it, but I eventually got something built with 2.15.2, and installed it. When I left click or double click on the applet, it doesn't lock up, but a menu doesn't pop up either.
Contrast this with the version 2.14.2: when I clicked on that, the applet and the neighboring system monitor applet would stop responding, but only for about 5 seconds. Not as bad as the bug description, but I remember older versions of the applet being worse, to the point where I'd have to kill the panel. Hope this is useful to know. -- Cpufreq applet locks up desktop with hand Icon (double click) or gnome-panel https://launchpad.net/bugs/22349 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
