I am assembling Landsat images into multispectral files by building virtual rasters for each scene.

There is a certain combination of options on the Build Virtual Raster dialog that always produces an error. On two different Linux Mint 17.3 machines, QGIS displays the following error when I run the function:

An error has occurred while executing Python code:

RuntimeError: wrapped C/C++ object of type QCheckBox has been deleted 
Traceback (most recent call last):

    enableInputFiles = not self.inputSelLayersCheck.isChecked()

On Windows 10, QGIS crashes on exit, with a minidump (attached).

As far as I can tell, it was introduced in the .1 release, so it looks like a regression.

Forgot to say that the attached screenshot shows the parameter values on the Virtual Raster dialog.
