-- Information about the crash:
- What I was doing when the application crashed:
After upgrade KDE NEON (Juin 03) : KDE connect crached every time. Along upgrade , error message ==>  Investigating (0) python3-pyqt5:amd64 < 5.14.1+dfsg-3+20.04+focal+build13 -> 5.15.4+dfsg-1+20.04+focal+unstable+build20 @ii umU Ib >.
Broken python3-pyqt5:amd64 Breaks on python3-pyqt5.qtwebengine:amd64 < 5.14.0-2build1 @ii mK > (< 5.15.0-1+exp1~)
  Considering python3-pyqt5.qtwebengine:amd64 1 as a solution to python3-pyqt5:amd64 38
  Added python3-pyqt5.qtwebengine:amd64 to the remove list
  Fixing python3-pyqt5:amd64 via remove of python3-pyqt5.qtwebengine:amd64

The crash can be reproduced every time.
