Problem with QT4 and gnuradio

[Yile]

I am running GNU Radio 3.7.10 and when I run my module I get the following error:
Generating: '/home/root/top_block.py'

Warning: This flow graph may not have flow control: no audio or RF hardware blocks found. Add a Misc->Throttle block to your flow graph to avoid CPU congestion.

Executing: /usr/bin/python -u /home/root/top_block.py

Unable to open locale C in ICU, error code 3
Traceback (most recent call last):

tb = top_block_cls()
File "/home/root/top_block.py", line 52, in init
self.restoreGeometry(self.settings.value("geometry").toByteArray())
AttributeError: 'NoneType' object has no attribute 'toByteArray'

Done
^C

Do I need a later version of qt?
thanks

Hi and welcome to devnet,

Are you using PyQt or PySide ?

AFAIK, the version of Qt has no influence with your problem. You're likely getting an invalid value for the geometry property from your QSettings object. Did you save that property once ?
