For the libglib debug package, try libglib2.0-0-dbg. This indeed looks like nm-applet is getting killed, most likely by the kernel's oomkiller whose job is to maintain enough memory on the system. It doesn't mean though that it's necessarily nm-applet leaking memory.
In case it's actually nm-applet leaking memory, it could be a good idea to try to run nm-applet in Valgrind to see how it uses memory in this case. Please see https://wiki.ubuntu.com/Valgrind for instructions on how to do this. ** Changed in: network-manager-applet (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/664763 Title: nm-applet crashes if there is no internet: Caught signal 15 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
