Test failures on master

[itziakos]

it looks that current master is failing this is probably have to do with changes in the travis-ci environment.

We've seen that occasionally. I thought it was due to slow timeout, but it still happens. It's due to selenium tests. I have no idea of the underlying reason (the tmp dir is correctly created and the profile is there). In fact, the error message is generally deceiving. When I checked the source code, it's actually due to a timeout in getting the browser up and running.

It has been happening more and more lately and it is annoying when working on a PR

[itziakos]

I am having a look at it

[stefanoborini]

@itziakos I see this plagues your PR #194 as well. I leave it to you then, but please keep me updated on the motivation.

@itziakos sorry but you are on vacation and I need this fixed now, as I have a bunch of PR failing due to this problem. Reassigning it.

Problem is due to an unsigned firefox xpi webdriver.
