jsignature.compressorbase30.js - Uncaught TypeError: Cannot read property 'split' of undefined #125

The issue occurs when attempting to decompress a signature with no data.. The fix is to check if "data" has any data before calling uncompressstrokes.

, pluginDecompressor = function(data, formattype, importcallable){
    if (typeof data !== 'string') return
    if (data.substring(0, acceptedformat.length).toLowerCase() === acceptedformat) {
        data = data.substring(acceptedformat.length + 1) // chopping off "," there
    }

--> if (data) importcallable(uncompressstrokes(data)); }

Original Exception from chrome debugger:
