Dear Lazyweb, some program keeps shitting randomly-named empty directories into my Library/Preferences/ directory. Any idea how to figure out what's responsible for this noise?

drwxr-xr-x    2 jwz  jwz          68 Nov  8 13:41 ›÷êi®øˇfi/
drwxr-xr-x    2 jwz  jwz          68 Nov  8 13:41 ›†êi®øˇfi/

Update: These turds are coming from the TWAIN plugin to Photoshop CS2. Deleting "/Applications/Adobe Photoshop CS2/Plug-Ins/Import:Export/TWAIN.plugin" fixes it. It was creating these directories every time Photoshop started up, without any actual scanning being involved.

Logging fs_usage didn't help: when the junk was created, it logged mdimport indexing them, but didn't log the creator process. Setting up an "alert" folder action on the Preferences folder was more useful.
