Before, when I the app was crashing whenever I refreshing the cache, it also dumped the crash report somewhere on my system. However, after that, I tried refreshing the cache without putting anything in the URL to see if it was a problem with the refreshing process. Everything went fine, so I tried refreshing with the URL again, but now instead of it crashing the entire system, it just doesn't even load the URL at all, it just refreshes it and says that there was no title keys while also deleting it from the options tab. I'm not sure if this would help you, but I thought I might as well put all the details together just incase someone else came along and might have some suggestions on how to fix this.
