Expected results:

Should start normally, like version gui-0.9.22 (the latest which runs ok).
Version 0.9.23 not tested

I have exactly the same issue. Same versions and all. I think the problem is cx_Freeze (as reported here upstream[1]) and was introduced into mozregression-gui at 0.9.24 via this commit[2].

By the way, I'm running Debian 9.5, with latest updates.

This sounds plausible -- unfortunately the commit was needed to make the GUI work again on Windows. I don't really have time to track this problem down, but would accept a patch/PR which addresses the issue.

Do you know if there is any information on how to create the standalone version from the source code? To be able to test an eventual PR.

I am getting the same error on gui-0.9.36 (Ubuntu 18.04 64-bit). This is preventing me from generating a regression range for bug #1524156.

[Oriol Brufau [:Oriol]]

As I workaround I was staying in version 0.9.22. But now Firefox has a profile downgrade protection which is only avoided since 0.9.36. Bisecting has become so painful.

Sorry, somehow I missed this. Thanks for the needinfo. There are instructions on building the GUI here:

https://github.com/mozilla/mozregression/blob/master/gui/README.rst

I am in the middle of porting mozregression to python 3, which will allow us to consider other bundling options (or make existing ones work differently) for the GUI, which I suspect may fix this bug. My work in progress is here:

https://github.com/mozilla/mozregression/pull/513

As part of this work, I could probably also take another look at the python gui. I probably won't have time to look at that again until later this week or early next.

I have the same bug in linux
python 2.7.15
