When I hover over a symbol in Kate, the tooltip is provided by the LSP. When I use the mouse button to double click the text and select it, Kate crashes. This is not exactly consistently reproducible but the common theme is to create a popup and then click on the popup or outside rapidly.

This has been reported to Qt as well https://bugreports.qt.io/browse/QTBUG-117015 where you can find the backtrace from all threads and a screenshot.
