Argos Translate GUI repeated delete breaks

[argosopentech]

I'm getting this error while using Argos Translate GUI which seems to be coming from Stanza:

Traceback (most recent call last):

Steps to reproduce

• Argos Translate 1.9.1
• Repeatedly uninstall packages by clicking on the trash can icon in Argos Translate GUI > Manage Packages
• After 5-10 deletes Argos Translate crashes
