Launching application using ilia causing regolith to be non-responsive, sometimes.

[CameronRP]

So about once a day this will happen:

1. Use ilia to launch an application
2. Start to type in the application name
3. Part way through typing the application name it freezes and my whole regolith session seams to just be non-responsive.

When this happened last I switched into a virtual console (ctrl+alt+f2) and I could see that journalctl was using a whole CPU core and the logs were filled up with lines like this.
ilia[2648405]: message repeated 230226 times: [ gtk_tree_model_filter_real_unref_node: assertion 'filter->priv->stamp == iter->stamp' failed]
I found that if I killed ilia using pkill I could return to my regolith session and it would all be back to normal. Could even start an application using ilia.
The ilia command that was running at that time was ilia -p apps -t /usr/share/regolith-look/nord/ilia.css

Same for me. When I looked at top in the console, I saw that ilia was using more than 20GB of RAM before I killed it.
