Comment 1 Christoph Feck 2014-05-19 20:01:29 UTC

Could be related to KAuth or power management, but the XIOError could also simply be an X11 bug. This is one of those bugs which can only be fixed if there are exact steps to reproduce or detailed valgrind logs.

Comment 2 Andrew Crouthamel 2018-10-31 04:01:28 UTC

Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond.

Thank you for helping us make KDE software even better for everyone!

Comment 3 Adam Stein 2018-11-01 14:10:06 UTC

Have not seen this bug since upgrading to Fedora 27

Comment 4 Andrew Crouthamel 2018-11-01 15:26:16 UTC

Thanks for the update!
