AttributeError: partially initialized module 'syncplay.vendor.Qt' has no attribute 'QtGui' (most likely due to a circular import)

To Reproduce
Steps to reproduce the behavior:

1. Start syncplay.

Expected behavior
Syncplay starts normally.

Version and platform:

• OS: Arch Linux 6.6.8-zen1-1-zen
• Syncplay version and build type: 1.7.1-2
• Media player and version: v0.37.0

Additional context
I'm a bit puzzled as to why I'm getting this error even when I'm not using the GUI... It even pops up when using -v or -h.

I'm on Windows and have PySide installed so it's a bit hard for me to investigate, but I'll do my best to help figure it out...

On line 12 of /syncplay/ui/__init__.py try changing except ImportError: to except (ImportError, AttributeError) as e:
and let me know if that resolves the issue.

This worked, thank you!!

Glad it worked. I plan to make those change to the main Syncplay repo to fix the issue for others as well.
