Description of problem: Evolution regularly just locks up my machine when reading messages - often when changing from one to the next. Gnome-shell itself stops functioning thereafter, with only the mouse moving, but not screen updates.

*** Bug 1589847 has been marked as a duplicate of this bug. ***
Thanks for a bug report. According to the var_log_messages the passed-in device was incorrect, which can be due to ref-unref imbalance. I do not know whether it is, it just can be.
I searched through the evolution code base and I didn't find any ref/unref imbalance on the GdkDevice pointers. This can be caused by some other issues too, like a use-after-free when writing to a memory which is already freed, or freeing it twice, which can overwrite basically anything what is at that memory part now. That can strike basically anywhere.
This message is a reminder that Fedora 28 is nearing its end of life. On 2019-May-28 Fedora will stop maintaining and issuing updates for Fedora 28. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '28'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 28 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 28 changed to end-of-life (EOL) status on 2019-05-28. Fedora 28 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
