Yes, simply handling it like any other invalid file would be good.
Sorry, I am only reading this now, so I have opened a bug after doing
some more debugging:
https://bugs.kde.org/show_bug.cgi?id=283412
The problem is an ininite loop in void RIFF::File::read() because
    uint chunkSize = readBlock(4).toUInt(bigEndian);
is always zero.
