It sounds like the same problem, only I'm not using ezdbfile (as far as I know) and the tables ezdbfile and ezdbfile_data are not present in my database. Instead of creating infinite 'trashed' entries in the database, it creates (apparently) infinte 'trashed' directories on the filesystem.
Ezwebin is checked as extension, but as far as I know little to none of the functionality is being used. Other than that I'm using the default EZP package. I didn't have this problem before upgrading to 4.4, does that help?
If you say you did not have this problem before upgrading to eZ 4.4, I'd say it sounds like a bug. My suggestion would be to submit it to the tracker (http://issues.ez.no).
I've not seen this before on the forum, or tracker, so can't provide you with a solution I'm afraid. I'll ping eZ Engineering, aks if they have seen this before and have a patch for it.
