Exceptions in Error log

Every time I load a page on my Orchard site I'm seeing multiple exceptions logged by Combinator in the App_Data\logs\orchard-error....log :

This is the first time I checked log, and it happens to also be right after I just rehydrated Orchard from a fresh db, fresh compile, empty App_Data dir, etc. My recipe includes Combinator, if that makes any difference. 

Is it possible to replace the code that's throwing this with a File.Exists check rather than letting it hit the exception, or something along those lines?

Hmm... The only way I can think of when that could happen if the DB cache and the file cache is in an inconsistent state, that means, the DB was wiped, but the file cache not or vica versa. This could happen if you either wipe the DB cache by hand, or the file cache; I think you've made the second: Combinator stores the files in the Media folder (well, it stores them with the IStorageProvider, but the default implementation happens to use the Media folder), so if you do a fresh install without emptying the cache first, but leave the Media/TenantName/Combinator folder intact, this error can happen. So either empty the cache first, or wipe the Combinator folder in Media too.

Actually there's no way to check file existence with IStorageProvider, but that shouldn't be an issue in that case.

Thanks -- that fixed it. I rehydrated the site and this time also deleted /Orchard.Web/Media/Default folder as part of my step to wipe out the existing install. 

I also voted the issue tracker request you linked to.

I also implemented the methods in a fork for a few weeks, currently awaiting core developers' reply.
