Sorry for the issues you've been experiencing. Just seeing these messages now and I've pushed a new version 0.9.3 which should address this issue.
I'm not sure why the update triggered this issue as it's been in the code for some time. I also wasn't able to replicate it locally, but it might be because I'm using an older PHP version.
Hopefully the issue is now fixed. I'll be watching this thread for the next few hours in the case of any further issues.
Again, apologies for the issue.
