The latest round of qt updates seem to have broken Nextcloud for me. While syncing works, once I actually go to view the GUI, an incorrectly formatted window opens and the program crashes (segmentation fault).

Since the version on the Parabola repos is modified a bit, I thought I should report the issue here first before opening an issue upstream.

Below you can find the backtrace:
