Every time I try to start my Minecraft, it shows this: java.lang.IllegalStateException: Could not load icon: Image not of any known type, or corrupt

Whenever I click start on Minecraft, it starts to download even if it has already downloaded the version before. After it downloads, the game automatically starts, as usual. Then, it suddenly crashes, and I am left with this: java.lang.IllegalStateException: Could not load icon: Image not of any known type, or corrupt. I also have the Minecraft Crash Report pasted into a pastebin.

If anybody can help me, that would be greatly appreciated.
