[Pkg-xfce-devel] Bug#762211: lightdm crashes on startup, system falls back to console

[parspes at gmail.com (Pat Parson)]

Package: lightdm
Version: 1.10.2-2
Followup-For: Bug #762211

Dear Maintainer,

I am having this problem again, this time liblightdm-gobject is not the apparent cause.
After updating lightdm to latest testing version I am having the same results but an error appears in the logs.
segfault at * error 4 in libc-2.19.so
