Receiving a TypeError while loading data

[Baris Baydargil]

   I've been dabbling around with Expresso for a few hours. Managed to install and run it without problems, but my problem arises when I try to load data in the Data View segment.
I followed the first tutorial on importing data. Managed to download the CIFAR data, however when I click on Load data and select $EXPRESSO_ROOT/tutorials/data/cifar_t1.hdf5 as the main data, I come across a Python error which reads

        self.lineEditFolderData.setText(self.dialogHandle.getOpenFileName(self,self.tr("Open File"),str(self.prevPath)))
        TypeError: QLabel.setText(QString): argument 1 has unexpected type 'tuple'

   Does anyone have any idea on how to fix this? Can't seem to find where the code is coming from either. Thanks in advance
