Spyder crash on launch with Babel 2.0/Python 3.4

[JGoutin]

Hello,

Babel was updated to 2.0, unfortunately, Spyder crash with this version. I gone back to 1.3 to fix that problem.

spyder_crash.log :

Thanks for reporting, we'll try to fix it ASAP :-)

I can confirm the error, but it seems a problem with babel, not with Spyder, at least according to

I confirm the problem and the fix listed above did not work

[jrminter]

The problem is indeed with Babel. I ended up downloading babel from github and building from source. Then I build spyder from github. all works now.

[ccordoba12]

Yes, the solution is really to downgrade to babel 1.3

Hi. I'm not sure. Is Babel 2.0 ok and functional with Spyder under Python 3.4 now ?

[ccordoba12]

If a TypeError is generated by Babel, then the Rich mode of the Object Inspector is deactivated.

The advantage is to avoid a crash at Spyder startup.

[stonebig]

ok. It looks better to stay on Babel 1.3, for Python 3.4 users. thanks
