Description animtim 2017-07-24 13:07:56 UTC

When building Krita git master on mageia6, I have this error message:

KeyError
Python 3.5.3: /bin/python3
Mon Jul 24 15:04:12 2017

A problem occurred in a Python script.  Here is the sequence of
function calls leading up to the error, in the order they occurred.

Comment 1 wolthera 2017-07-24 15:20:29 UTC

default is the palette named default... why don't you have this?

I mean, I can try to get the last selected palette from the config, but honestly, why don't you have the default palette?

Comment 2 wolthera 2017-07-24 15:29:02 UTC

Git commit 81fda7a88f945f3d71cd8cd4a4b29555a515a688 by Wolthera van Hövell tot Westerflier.
Committed on 24/07/2017 at 15:28.
Pushed by woltherav into branch 'master'.

Pick the first palette in the list always to prevent crashes.

But why are people missing the default palette?
