[RESOLVED] Installing GTK theme freezes the whole system

[Max Gene]

Hey everyone. Bit of a weird problem here... I tried to install Azenis, a particularly snazzy theme, via Preferences -> Appearance. Now, I know Prefs/Appearances can install other themes because I've already done it on this install; but when Azenis gets installed, the system freezes entirely. No virtual consoles, nothing. Where would I even start to look in order to diagnose what's causing this?

EDIT: For reasons unknown to me, installing again resulted in it freezing again, but everything worked on reboot. I'm curious as to why if anyone can answer that, but I'm happy that it's working.
