Title:
  pavucontrol segfaults when closing with [CTRL]+[q]

Status in pavucontrol package in Ubuntu:
  Confirmed

Bug description:
  When closing pavucontrol with the [CTRL]+[q] keyboard shortcut, it
  directly segfaults. The problem affects both Ubuntu 20.04 (pavucontrol
  4.0-1build1) and 20.10 (pavucontrol 4.0-2) and can easily be
  reproduced (tried it on two different machines and also in a VM).

  From the crash dump (also uploaded one via the crash reporting dialog,
  don't know if anyone is actively analyzing crash uploads for universe
  packages there):
