Tor Browser crashing on startup

Help

Tor browser crashes on start with the following output. I installed tor-browser-bundle-bin as a system package. Is there something I need to do in addition or something I need to do differently?

My prior two queries were answered within a day. Bug perhaps?

I found this issue with a possible workaround. As a complete newb, how do I set useHardenedMalloc = false?

When you normally add a package without overrides, it would look like:

environment.systemPackages = with pkgs; [
  tor-browser-bundle-bin
]:

With overrides you can override the inputs to a package. Inputs are all the tings in the curly braces at the top.

See tor-browserbundle-bin/default.

For this case the override should look like this:

environment.systemPackages = with pkgs; [
  (tor-browser-bundle-bin.override {
    useHardenedMalloc = false;
   })
]:

Many thanks! That seemed to do the trick, at least from the terminal. I also had to switch the installation of tor-browser-bundle-bin to the unstable channel.

One niggling little issue: it won’t start from Gnome dash. When I try to start it via Gnome dash, an icon shows up in dash but no browser window and then the icon disappears.

Restart the gnome session by logging out or restarting.
