In reply to Mathieu: It usually takes days, not hours, before I notice the problem, but I think I have never gone more than three days without. I have run an instance of valgrind --leak-check=full --trace- children=yes --log-file=nm-applet-%p.log nm-applet in a console and hit Ctrl-C when I noticed the problem. I'm attaching a bzip2 compressed log file.
The console output was --snip ** Message: applet now removed from the notification area (nm-applet:10742): GdkPixbuf-CRITICAL **: gdk_pixbuf_composite: assertion `dest_y >= 0 && dest_y + dest_height <= dest->height' failed ** Message: No keyring secrets found for WLAN-001A4F3AD299/802-11-wireless-security; asking user. ^C** Message: PID 0 (we are 10742) sent signal 2, shutting down... --snap (Note: The "No keyring secrets" message is related to a different problem.) ** Attachment added: "Log generated by valgrind --leak-check=full --trace-children=yes --log-file=nm-applet-%p.log nm-applet" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1011073/+attachment/3251319/+files/nm-applet-10742.log.bz2 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1011073 Title: NetworkManager submenus sometimes unpopulated Status in “network-manager” package in Ubuntu: Incomplete Bug description: Submenus in Network Manager are sometimes unusable as they are not populated. This happens both with the list of available networks and with the VPN list. When the bug happens, it occurs for *both* the wireless submenu and the VPN menu. I know there are entries for those submenus as I can see them with other network UI mechanisms. The issue is intermittent. Expected: Dropping down the menu then hovering over the submenu trigger-point (example: "More networks") shows the additional expected entries (example: more wifi networks to choose from). Actual: Dropping down the menu and hovering over the submenu trigger displays a submenu but the submenu has nothing in it and is unusable.
