The code below is crashing in MeterFilter::PutMaybeModifiable

9 Hash::aesEncryptFilePump() hash.cpp 315 0x10000ecf0
after calling
aesEncryptFileOpen(QString inFile, QString outFile);
aesEncryptFilePump()
is called, to start it then the GUI keeps pumping. I don't know why the
MeterFilter should _ever_ crash? readLength is 65536.
