    Appreciate explanation of how to have empathy work again, and whether a need to be concerned, or not..

    Default Re: Empathy opens and closes,

    Learn this reading about segfault (Segmentation Faults) from http://rgeissert.blogspot.com.au/201...lt-errors.html

    Then using error 4 on page: http://rgeissert.blogspot.com.au/p/s...ult-error.html


    Where
    the error codes enum from the linux kernel's arch/x86/mm/fault.c source code file.
    and did learn the
    cause was a user-mode read resulting in no page being found.

    Seems both actual and links are there.

    What is a user-mode read ?


    Code:
    linux-30s5:~ # dir   /usr/lib/libglib-2.0.so.0.3800.2
    -rwxr-xr-x 1 root root 1072080 Nov 25 21:50 /usr/lib/libglib-2.0.so.0.3800.2

    linux-30s5:~ #
    Code:

    -rwxr-xr-x 1 root root 1057936 Nov 25 21:37 /usr/lib64/libglib-2.0.so.0.3800.2

    ld: warning: cannot find entry symbol _start; not setting start address
    linux-30s5:~ #

    Self incorrectly reading ld (LD) when should be id (ID)


    Code:
    linux-30s5:~ # id  /usr/lib/libglib-2.0.so.0.3800.2
    id: /usr/lib/libglib-2.0.so.0.3800.2: no such user
    linux-30s5:~ # id   /usr/lib64/libglib-2.0.so.0.3800.2
    id: /usr/lib64/libglib-2.0.so.0.3800.2: no such user
    linux-30s5:~ #

    Yet see dir showing user:group as root:root ?
