Subject: [PATCH] Fix use-after-free bug

QByteArray::fromRawData() does not copy the contents of the source
buffer. If the resulting QByteArray object lives longer than the source
buffer, we run into use-after-free problems.

In this particular instance, the source data resides in a temporary
rvalue object.
