Pharlap on Gnome 23 fails to initialize properly

[exif]

Running on my Korora Gnome 23 beta installed to a physical drive, Pharlap is failing to launch properly.

When run by normal user:

Pharlap window opens, but there are no contents, just a blank white surface; no initialization progress is visible and it stays in this state indefinitely; exits normally when the window is closed

Output from launch to closing the window manually when run from terminal:

[12:53 eg ~]$ pharlap
/usr/lib/python3.4/site-packages/lens/appgtk.py:28: PyGIWarning: WebKit2 was imported without specifying a version first. Use gi.require_version('WebKit2', '4.0') before import to ensure that the right version gets loaded.
  from gi.repository import WebKit2, Gio, Gtk, GObject, Gdk

When run with root privileges:

Pharlap window opens normally and displays the "Reading repository information ..." message, but does not progress beyond this point; the progress bar does not fill and there is no animation; stays in this state indefinitely and exits normally when closed

Output from launch to closing the window manually when run from terminal:

[13:07 eg ~]$ sudo pharlap
/usr/lib/python3.4/site-packages/lens/appgtk.py:28: PyGIWarning: WebKit2 was imported without specifying a version first. Use gi.require_version('WebKit2', '4.0') before import to ensure that the right version gets loaded.

This didn't happen to me on the XFCE spin; Pharlap launched properly there.

I don't seem to be able to attach labels, or maybe I am just doing something dumb

@firnsy ping

@exif with Lens applications (not that you you knew pharlap was one) one can now receive extra debugging by adding the LENS_DEBUG=1 environment variable.

It's not necessary to update this with the debug information, I'll take this issue from here

[exif]

@firnsy Thanks, I'll try that next time

[firnsy]

@exif, after a fresh install on real hardware i can't reproduce this bug. can you confirm you've done a full upgrade and rebooted?

[exif]

@firnsy Yeah, this was after a fresh install from the beta ISO and running dnf upgrade, then rebooting (actually rebooted due to a nouveau crash, seems like it was a -pie rebuild thing); at this point I had made some changes to the default software configuration, but I hadn't touched any dependencies of Pharlap. I'll test the Gnome ISO on a virtual machine again and retrace my dnf transaction history to see if it's something I did.

[firnsy]

Closing due to non-reproducibility.
