Bug 452618

Application: kile (2.9.93)

Qt Version: 5.15.3
Frameworks Version: 5.93.0
Operating System: Linux 5.13.0-39-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.24
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

I wanted to select text in my PDF preview, so I clicked the "Browse" button to switch to a text-selection tool. I get the same crash behavior when I restart Kile.

The crash can be reproduced every time.

-- Backtrace:
Application: Kile (kile), signal: Segmentation fault
