Hi Kluu,
This error appears when checking the "Do not compress target file" option when building an application. The workaround is to not check that option in Application Builder.
While in the application builder, in the "Target" tab, in "Build Options", do NOT check the "Do not Compress Target File" option.
We are currently looking into this and will soon be fixing it up.
Hope this helps.
