I'm using Ubuntu 16.04 as well and I get the segmentation fault if I open any keyboard shortcut window, even if I click the Cancel button without making any changes.

I don't know if it's helpful, but I ran gdb and recreated the error:

Thread 1 "python" received signal SIGSEGV, Segmentation fault.
0x00007ffff2c0816e in QMetaObject::activate(QObject*, int, int, void**) ()

Sorry, I wasn't trying to report a bug, just trying to help provide debugging information. But, here are my versions:
[Python 3.6.3 64bits, Qt 5.6.2, PyQt5 5.6 on Linux]

Thanks @csabella!

[ccordoba12]

@csabella, is this still an issue for you?

[csabella]

@ccordoba12 It still happens on 3.x, but does not happen on master.

[ccordoba12]

I can't reproduce this in Kubuntu 17.04.

On the last update, I said it wasn't happening on master, but now it's happening on master for me, as well as 3.x and the release version of 3.2.5.

I open Preferences, then Keyboard Shortcuts, double click on 'Find Next/F3', press F4 for the new shortcut, and click OK. It closes Spyder and gives a seg fault. I looked at this a little bit when it was first reported, but I'm going to spend some more time on it now to try to track it down.

Thanks Cheryl! I don't think this is going to be easy to fix...

Had this with sypder 3.4, solved it with spyder 3.6. Try conda update spyder
