jcooper@m2:~$ python Desktop/thumbnail-checker.py
Traceback (most recent call last):
File “Desktop/thumbnail-checker.py”, line 181, in ?
locale.setlocale(locale.LC_ALL, lang_code)
File “/usr/lib/python2.4/locale.py”, line 381, in setlocale
return _setlocale(category, locale)
locale.Error: unsupported locale setting

This is on a Dapper machine that should, in theory, have the python locales configured correctly. Any advice to offer?

Thanks in advance if you do :)

You don’t need to make it “hard” to guess the corresponding URI.

Independently of the hash chosen, a nice idea would be to have two files for each thumbnail:
- “[hashed-URI].thumb” containing the thumbnail itself
- “[hashed-URI].URI” containing the URI of the file

That would allow for some background tool that would clean up stale thumbnail files.
The TTL value could depend on the URI type (e.g.: longer for file that exist, shorter for http URL)

Just food for thought…

Could you just add a delete option to your script?

By the way, u made a very good job.

Be nice, it’s the first Python programming I’ve ever done in my life, so I’m sure it violates lots of Pythong conventions.
For deleting you can either select a row entry and use the delete key or just use the Remove All button.
I’ve tried to do a moderate amount of testing on this, however I didn’t have any “thumbnails” of the External or Invalid type.
