Summary

Hello
since a while I'm unable to open the budgie control center. When I try to start it via console I get the following error:

(budgie-control-center:10012): GLib-CRITICAL **: 15:45:13.169: g_strsplit: assertion 'string != NULL' failed
Speicherzugriffsfehler (Speicherabzug geschrieben) budgie-control-center

Steps to reproduce

1. Type budgie-control-center in a console

Expected result

Control center should open.

Actual result

(budgie-control-center:10012): GLib-CRITICAL **: 15:45:13.169: g_strsplit: assertion 'string != NULL' failed
Speicherzugriffsfehler (Speicherabzug geschrieben) budgie-control-center

To see what's going on, we're going to need to see the full backtrace with symbols.

1. Install debug symbols

   sudo eopkg it budgie-control-center-dbginfo libgtk-3-dbginfo glib2-dbginfo

2. Install gdb

   sudo eopkg it gdb

3. Open the latest coredump for Budgie Control Center

   sudo coredumpctl gdb budgie-control-center

4. Type the following commands to save the backtrace to a file

   set logging file <path/to/file>
   set logging enabled
   backtrace full

Then, copy the contents of the saved file here, between three backticks, like so:

```
Text here
```

It looks like libcheese and/or cheese (an old GNOME utility to take a picture with a webcamera; it's been unmaintained for years now) is crashing. What is the last thing you did in the control center before it stopped working?

[gerdfa]

I can't recall - when I last used the control center and what I did there.

You are also right that cheese is crashing:
