[systemd-devel] systemd-coredump[2529]: Process 2326 (xfwm4) of user 1000 dumped core maybe because of lightdm[2482]: gkr-pam: unable to locate daemon control file

[Linuxfreak at gmx.at]

Hi,

i do not know who is the correct person / mailing list, to ask for this one.

1) screen-lock locks the screen  (OK)

2) screensaver comes and screen is going to be black.  (OK)

3) Everytime i unlock my locked screen (after the screensaver kicked in) 
i got this:*systemd-coredump*   (NOT OK)


What are the next steps to fix this?

regards LF
