--- Comment #3 from Christoph Feck <cfeck at kde.org> ---
Base64 encoding will the file grow to 1105 million characters. With Qt's QChar
being 16-bit wide, it will need 2210 MB space, but Qt's containers only allow
2147 MB (2^31 bytes).

In other words, the backtrace will most certainly be the same as other
backtraces that document failed allocations from QArrayData::allocate().
