It’s annoying having to delete the entire Textures13.db+Thumbnails folder to try and correct scraping errors and/or corrupted images that just never go away, so I’ve written a very trivial Python script that can be used to interrogate the texture cache database, and can also be used to remove – with absolute precision – those database rows and cached files that relate to problematic artwork.
The script has been tested with local installations of XBMC Frodo on OpenELEC R-Pi and Ubuntu 12.10, and also Windows with Python 2.7.3 running against a remote Frodo installation of XBMC. A separate properties file can be used to specify non-default configurations (see property file details at the end of this post).
This is not an addon, and it requires that the webserver is enabled in XBMC on port 8080 (unless another port is specified in the properties file). It also assumes you are comfortable working at the command line (ssh in Linux, a large CMD window may also work OK for Windows users).
