instantbird crashes due to not finding compatible GRE

[GreatBunzinni]

After installing instantbird and trying to run it, the following message is printed to the console:

<message>

Could not find compatible GRE between version 2.0 and 2.0.0.*.
</message>

It would be great if it was possible to run instantbird
