I will guess and say that the problem would be with Guitar Pro.
Run it from terminal and post it (using pastebin) here. Maybe this will help to identify.

I am on "4.6.2-1-ARCH x86_64 GNU/Linux" and this isn't working although I reinstalled libpng12 and lib32-libpng12 libraries. Guitar Pro crashes when I open new score.

Does this package actually depends on libpng12?

delete old files from the directory and redownload.

@michaelgod: Why do you want to download the source files in the prepare function? Do you even know what makepkg does? It is up to you to have a working download agent in makepkg.conf. Also, please use a pastebin next time.
@Thorleif: sourceforge has since ever provided shortcut URLs for their download mirror system. As long as you know the project and the file's name, it will redirect you to the right URL.
For example this also works:
However, when the site is in recovery mode (which it has been quite often lately), it does not work, but in this case it is better to avoid it entirely and use another mirror.

The source file URL looks to be incomplete. It should be:

bmbaker: Did you build it yourself or do you use alucryd-multilib repository? Check 'LocalFileSigLevel' in your /etc/pacman.conf. Maybe you enabled signature checking for packages that you build yourself?

Hi there,
I was just doing my updates and got this error from your package,

(84/84) checking keys in keyring [######################] 100%
(84/84) checking package integrity [######################] 100%
error: lib32-libpng12: missing required signature
error: failed to commit transaction (invalid or corrupted package)

i did the usual,
sudo pacman -Scc
sudo pacman -S archlinux-keyring
sudo pacman-key --init
sudo pacman-key --populate archlinux
sudo pacman-key --refresh-keys
sudo pacman -Sc
sudo pacman -Syyu
but the error persists
