Status changed to 'Confirmed' because the bug affects multiple users.

Just tested in virtualbox, and can confirm the same error.

Also would note from kununtu-devel mailing list this mention

[Rik Mills (rikmills)]

For the time being a rather crude workaround is:

- boot to the live session
- launch konsole and do 'sudo apt purge ubiquity-slideshow-kubuntu'
- run installer as normal

Slideshow will not get invoked, so no need for PyQT5webkit, so no crash.

There may well be a command line option for ubiquity to achieve the same, but I'm not aware of it if there is.
