Description of problem: The offending program seems to be Lotus Sametime 8.5.2 IFR. Steps to reproduce (worked two out of two times for me): 1. Search for a contact using the search box 2. Right-click the contact and select "Add to contact list..." 3. In the following dialog, pick a group to add the contact to and hit OK As soon as I hit OK, the screen freezes with the OK button in the depressed state - the mouse cursor freezes as well. I'm sure Sametime is doing something weird to GTK here, I've had sporadic desktop freezes in the past too, but never as reproducible as this.

This message is a reminder that Fedora 27 is nearing its end of life. On 2018-Nov-30 Fedora will stop maintaining and issuing updates for Fedora 27. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '27'. 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 27 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 27 changed to end-of-life (EOL) status on 2018-11-30. Fedora 27 is no longer maintained, which means that it will not receive any further security or bug fix updates.
