Public bug reported: Binary package hint: gdm
After today's update, gdm crashes at startup. Didn't happen with lucid upated 2 days back. With libglib2.0-0-dbg package installed, gdm spits out following backtrace (started manually, but the same happens if spawned from upstart or run from inside gdb); note that at #9 g_idle_dispatch receives dispatch=0, which is pointer to function that is called, obviously resulting in crash. Fell free to ask for more information. gdm[2531]: ******************* START ********************************** gdm[2531]: [Thread debugging using libthread_db enabled] gdm[2531]: 0x0053c422 in __kernel_vsyscall () gdm[2531]: #0 0x0053c422 in __kernel_vsyscall () gdm[2531]: #1 0x0025ad23 in __waitpid_nocancel () from /lib/tls/i686/cmov/libpthread.so.0 gdm[2531]: #2 0x08066b19 in ??
