For the curious: it turns out that the invoke call that is done by
handleCallback may fail, and return before it has initialized the browserResult
variant to anything that makes sense. As it happens, in 64 bits Linux the
variable ended up being considered to be of type string, but obviously failed
to have a correctly malloc'ed string as the data, so free was called in
unrelated memory, causing the corruption.

As to why my fix to parseDataUrl exposed the problem, the URL notification was
the cause for the call that calls invoke. Since we were not setting an URL in
the response, no notification happened.
