I use an awsome collection organizer called Tellico. This is a KDE application that will run on Mint (Gnome) without any problems except for one. When I create a new entry (say for my CD collection), it gives me the ability to add a picture of the album cover. When I go to select the picture I want, the application is supposed to give me the ability to preview the picture before I select it. Unfortunately, in my case, I don't get the preview picture and, instead, get a generic "broken link" looking icon.
A few years ago when I was trying out Ubuntu and was having the same problem, I managed to find an easy fix for this issue just by searching the internet. For some reason I never saved a document of the fix and now I can't seem to find the fix online anywhere.
I'm hoping someone here knows what I'm talking about and can pass the solution on as it's driving me crazy. Everything else in the program works flawlessly except for this which is really important when you're cataloging 100's of CD's.
