OK, should be fixed now. I use pacaur to install AUR packages and noticed it seems to keep the source tar.gz for every version ever installed. I install masterpdfeditor a lot, so must have hit some kind of file limit, so the old incorrect checksum worked, but the correct one didn't, which is why I didn't catch this immediately. Deleting all the old copies resolved the issue.
Also, thanks for the heads up.
