"show_piecesbar" : triggers segmentation fault if not running "deluge debug"

[schmidttyd]

Deluge opens and behaves fine while "show_piecesbar" is false. If I change the setting "Show a pieces bar in Status tab" in the interface, it crashes Deluge just after a fraction of a second of seeing the pieces bar.

Oddly enough, everything looks and behaves (from what I can tell) perfectly fine if I open Deluge with "deluge debug".

$ deluge -v
deluge 2.0.3
libtorrent: 1.1.13.0
Python: 3.8.2
OS: Linux Pop!_OS 20.04 focal

[schmidttyd]

deluge -L debug

[ffe03e]

I can confirm the behavior. Here's the TestCase: 1) show_piecesbar=true 2) download something. 3) close deluge 4) move the downloaded file so it cannot be 'fast resumed'. 5) crash 6) edit show_piecesbar=false 7) no crash

Hopefuly the syslog backtrace helps with pinning down the issue:
