Spyder: Fontconfig error

[Atcold]

Description

What steps will reproduce the problem?

1. Run spyder from Terminal, in Ubuntu 16.04.

What is the expected output? What do you see instead?

The program opens up, but I get the following error messages:

Fontconfig error: Cannot load default config file
Fontconfig error: Cannot load default config file

Please provide any additional information below

If I browse the Plain text font I get on the terminal the following lines

Failed to compute left/right minimum bearings for "decsess.pcf"
Failed to compute left/right minimum bearings for "cursor.pcf"
Failed to compute left/right minimum bearings for "deccurs.pcf"
Failed to compute left/right minimum bearings for "micro.pcf"

Here is how the whole looks like.

@mingwandroid, this looks like a change in the Qt Anaconda packages. Could you give us a hand here? Thanks :-)

I also get

Fontconfig error: Cannot load default config file

but not the 'minimum bearings' warnings

I'm using Anaconda as well. Defaults fonts have changed for me, I'm unsure what they were before the update.

[mingwandroid]

Yeah I'm on it.

[ccordoba12]

Thanks!

[Atcold]

Just for reference, matplotlib is complaining about the same thing.

[mingwandroid]

conda update fontconfig should fix this.

[harryhobson]

@mingwandroid thanks, update fixes message for me.

[ccordoba12]

Thanks @mingwandroid for the quick response :-)

[Atcold]

@mingwandroid, worked for me as well. Thank you!
Sorry for the late reply, but I caught a flu and got back to my desk only today.
Would you mind sharing the fixing commit hash?

[ccordoba12]

@Atcold, the fix was not in Spyder but in the fontconfig conda package (which is maintained in a private repo).

[Atcold]

@ccordoba12, oh, thank you. I thought it was all open sourced...
