Sidenote: The "l" command shows code from src/nm-manager.c:824, instead it should show libnm/nm-manager.c:824. Something is wrong with the paths for the source files and the debug information. Note that core daemon (src/nm-manager.c) does not ues libnm (libnm/nm- manager.c). So, these two should not be in the same backtrace. Anyway, that is not really the issue here, just a bit confusing at first. The backtrace is still helpful... Thomas
