** Description changed: Binary package hint: lightdm On an Oneiric i386 system, I updated a number of packages yesterday (/var/log/dpkg.log attached compressed as dpkg.log.gz), and was given the choice between remaining with gdm (2.32.1-0ubuntu5) as my display manager, or switching to lightdm (0.3.7-0ubuntu1). I decided to try out lightdm. It appeared to work without problems, and defaulted to my default gdm session type as desired. But immediately after log in (to a unity-2d session), Apport informed me that lightdm had crashed with with SIGSEGV in g_child_watch_dispatch(). I don't have any more information, except that this bug looks similar to bug 795050, which is a SIGSEGV in a similar bug different dispatch function (g_main_context_dispatch()). But I did *not* also experience - bug 795050. + bug 795050. Also [UPDATE], bug 795050 has been fixed in lightdm + 0.3.7-0ubuntu2, whereas this bug still occurs with that version.
