new version of qt has come out, is that it?
Comment by Jelle van der Waa (jelly) - Sunday, 25 February 2018, 15:20 GMT
I can open stl and gcode files, is your system up to date?
Comment by Renato Caldas (rmsc) - Sunday, 04 March 2018, 18:39 GMT
I believe I can reproduce this bug, and it's also present in master. In my case it happens immediately at startup though.

I was able to workaround it by downgrading python-pyqt5 to the previous version (5.10-3).

Same problem here (crash on startup).
It seems this introduces the problem: https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/pyqt5&id=794c5cc581afe0d95bc530fb1f95c6a0b689f9d9
Downgrading python-pyqt5 to 5.10-3 solves the problem on my side

Sorry for the "me too" post, but I can confirm this problem (crash on startup) with the suggested downgrade of pyqt5 also solving it for me.
Comment by Jelle van der Waa (jelly) - Sunday, 11 March 2018, 20:42 GMT
Yup, I'm aware of the issue, sadly not much time to look into it.
Comment by Moabit (Moabit) - Saturday, 17 March 2018, 07:50 GMT
For me, I can't even launch cura itself. Downgrading to python-pyqt5 5.10-3 also fixes it for me.

I can also report that I get the same issue with cura-git from the AUR too, with the same fix working.
Comment by Jelle van der Waa (jelly) - Saturday, 17 March 2018, 13:01 GMT
Yes PyQt is somehow broken
Comment by Aaron Fischer (aaronmueller) - Sunday, 18 March 2018, 19:25 GMT
I understand if there is sometimes things in life, which are more important than this, but the package is completely unusable/broken at the moment. If this is a AUR package, ok, but it is a official community package.

A temporary workaround is postet and verified several times here, so why not just pin the python-pyqt5 package to the version needed. I know, this is not the best way to deal with it, but better than installing a broken software and let the user search for hours and finally find this bug report here to solve the problem.
Comment by Eli Schwartz (eschwartz) - Monday, 19 March 2018, 05:05 GMT
Because the old pyqt5 package is no longer available on the mirrors, so it would be very nearly the same thing as simply pulling the package from the repos altogether?

Might make more sense to try chasing down the issue yourself e.g. see https://www.riverbankcomputing.com/mailman/listinfo/pyqt

https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/pyqt5&id=2126378a110aab1422cec64426eb4ca979dfc968

pyqt5 5.10.1-2 has been patched to fix the cura crash at startup.
