Apparently in the Italian version of 6.4 there is a regression in the locale that causes the toolbar buttons in message filters not to display. Instead there is an xml error in Betterbird:
I believe this is caused by escaped double quotes. I couldn't reproduce it at first because in the current prerelease 6.5pre5 this is already reversed to using lexical quotes:
Here is a quick fix version:
quickFilters-wx-6.5pre6.zip
To install version above download zip file and drag the file into Add-ons Manager (do not extract contents, it won't install like that) - also restart Thunderbird for this one so that the new style sheet will be loaded.
