wf-dock crashes when monitor turns off and then it turns back on

[je-vv]

Using plain wayfire with plugins-extra and wf-shell with wf-panel and wf-dock. Versions:

• wayfire 0.9.0
• wayfire-plugins-extra 0.9.0
• wf-config 0.9.0
• wf-shell 0.9.0

Installed from AUR and running on artix gnu+linux. The full gdb log with backtrace at the end:

From the error and part of the BT it seems the segafult is caused when trying to use a pointer which was already removed:

Thread 1 "wf-dock" received signal SIGSEGV, Segmentation fault.
WfToplevel::handle_output_leave (this=0x5555557a0910, output=<error reading variable: Cannot access memory at address 0x8>) at ../wf-shell-0.9.0/src/dock/toplevel.cpp:99

No idea why that might be and that originates from:

#59 0x000055555556228b in WfDockApp::create (argc=1, argv=0x7fffffffdf18) at ../wf-shell-0.9.0/src/dock/dock-app.cpp:137
