Ouch, you can't call data() here, that's keeping a char* pointing to a deleted (temporary) QByteArray.
The .data() calls need to be inside the getxattr calls themselves (so that filenameEncoded is a QByteArray, which controls the lifetime of the 8bit string).

Hmm, that makes a lot of sense, actually :-)
