File cannot be used as application icon error

Bugs and Other Issues
1

I am trying to build an app which has built fine in the past, but now it fails during the "Preparing application icon" stage with the following error.

App Inventor is unable to compile this project.
The compiler error output was
________Preparing application icon
.

A few seconds later, the following alert pops up at the top of the screen, then quickly disappears.

In the media list, the file is listed as download%20(26).png but the error says download (26).png, so this could be an encoding issue.

What gives?

Changing the name to have no spaces or % escapes makes it build correctly.
