Seem to be having a strange issue in kali 2017.3 MATE:

Running gnuradio and generating any QT GUI flow just gives the following error:

traceback (most recent call last):
File "/root/", line 96, in <module>
File "/root/", line 84, in main
tb = top_block_cls()
File "/root/", line 53, in __init__
self.restoreGeometry(self.settings.value("geometry ").toByteArray())
AttributeError: 'NoneType' object has no attribute 'toByteArray'

Have reinstalled twice and just done a straight apt-get install gnuradio incase anything installed had messed it up but its still the same.

Anyone else seen anything like this? Has the version of gnuradio in the repos changed recently?
