The same issue was found originating from KSvg code in Bug 487230. Looks like it's still asserting in the same line of code, so I guess that change was not enough. *** This bug has been marked as a duplicate of bug 487230 ***
Actually my mistake, it's slightly different. Now it's asserting because the size() of the QRect is empty.
Can you explain better your steps to reproduce the issue? The way I understand you did the following: 1. Start the computer. 2. Log into your account with kde. 3. Change the display from hdmi to display port. If that's what you did, how did you change your display? You plugged and unplugged the display with a different cable or did you switch between different monitors already connected?
