Hi @cmon1701 , thanks for the bug report. I am unable to reproduce this myself. Did I miss a step?

1. install the dracula theme
2. set the dracula theme
3. run ilia

Hi @kgilmer,
the error only occurs about once a day, not every time I use Ilia. That makes the error not so easy to reproduce, I guess.

Ah ok. I did look around the code but didn't find any obvious problems w/ icon handling. From searches it seems that people see crashes like this in other programs from snap-packaged apps. Kindly update the ticket if you find a way to reproduce the problem reliably, thanks!

I found a way to reproduce it!
It happens about every third time when I do this call from command line:

❯ ilia -p apps

Hi @kgilmer, the error only occurs about once a day, not every time I use Ilia. That makes the error not so easy to reproduce, I guess.

I have to correct my statement : The error does occur more much often, about ever third time. By command line call or Win+Space (just nothing happens when the error occurs). I only get the Ubuntu error window about once a day (and it seems that the corresponding file /var/crash/_usr_bin_ilia.1000.crash is only written once a day).

I have a similar problem. When I run ilia from command line, I see this error

ilia -p apps

Note that if I run ilia -p keybidings -a, there is no such problem.

A walk around is to change Icon in gnome-tweak from Highcolor to Adwaita.
