Thumbnails Are Not Being Created For PDF Files


I have been facing this problem in the last couple of months: PDF files are not having their respective thumbnails created for them. That's kinda strange because this problem only happens for PDFs. Other media are OK and having their thumbnails being created for them.

I would appreciate any help from you, guys and gals!



Try the default icon set. It might be that you use an icon set that has no redirection to the default set for missing icons but all other icons are covered.
On the other side, I noticed in my tests in my Virtualbox, if you customise a default icon only once, its connection might be broken for ever.
