Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 5.3.7-arch1-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I opened Kile, clicked 'File > Remove template', and selected a template I had previously created.

The crash can be reproduced every time.

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