Description
I occasionally encounter a segfault while using Qt Creator 12.0.0. I have not observed this problem before upgrading to version 12.
The most recent time I hit the problem, I was switching files in one of my editor panes. I had used ctrl + shift + R to navigate to a file. I selected the file and the editor changed to the contents of the file, but almost immediately afterward the entire program crashed to desktop.
I have attached the relevant contents of Journalctl. The most relevant bits are:
