Errors with 3.0.7

I updated to 3.0.7 last night and suddenly everything seemed to slow down, lots of beach balls. Got a bunch of Hazel errors through Growl that look more or less like this, but with various files and rules:

Hazel - Error during rule evaluation
Received error while trying to evaluate rule Run on files on file Bus schedule.zip.pdf

These all seemed to be working fine before the updated. The Hazel log has lots of:

Any ideas what happened?

I am experiencing the same issues. Please help.

Same here.
I have some rules which look at the content of pdf files to rename them. The rules no longer work...

ditto.

In my case its happening with some openmeta tagging rules applied to old .emlx files, which have been tagged before - but Hazel seems to want to tag them again (by the hundreds) .. and they all return these errors.

Same here.

Please email support with your rules (click the contact support button in the Info section).

I'm having the same problem.

I'm seeing tons of Growl error messages since the recent update as well. Same error, same rule, same folder:

OK paused that Downloads folder to test, and now I am getting the same error from another folder. Has the Date Last Opened rule in common:

I've issue a patch which should hopefully fix this (I say "hopefully" since I received very few actual rules for me to test against). Please update and report back.

I just emailed you a set of rules for one of the affected folders. Did the 3.08 update and will let you know how it goes.

New issue with 3.08 installed, not sure if 3.08 caused this or not but worked fine prior to 3.07.

The first rule is not being matched:

I believe you already have my rules for this folder when troubleshooting via email earlier today. Subsequent rules match OK. Again seems date-related.

Nix that previous post with new error, now it seems to be working fine. Odd.

Sorry, got busy at school and didn't see your reply until just now.

Installing the update. If I still have the error, I'll email in the rules.
