Related Application and/or Package Version (run apt policy $PACKAGE NAME):
Pop!_Shop

Issue/Bug Description:
The Pop!_Shop crashes when interacting with packages in a certain way. I could (only) reproduce it with the discord package, but I doubt it's limited to that.
When you search up Discord and try to change the package type from flatpak to system package, the Pop!_Shop just crashes.
Similarly, when you install Discord via .deb and then click on the package within Pop!_Shop, it crashes.

Steps to reproduce (if you know):
Search up the Discord package in Pop!_Shop. Change from Flatpak to .deb.
Alternatively: Install Discord from their website as .deb, then also search it up in Pop!_Shop and click on it.

Expected behavior:
It just changes the package install type so I can install Discord as system package
//
I can view the installed .deb package like any other

Other Notes:
Could not find any other packages this happens with in the limited time I had, so, may or may not be limited to the Discord package

Our development is now focused on cosmic-store, which you can try out today.

I can recreate this. This is a pretty weird issue, given that we specifically package Discord as a .deb in our proprietary repo (since the Flatpak has issues with game activity functionality).

Based on gdb output, this is likely the same issue as #439.
