Linux: Installer failing with "basic_string::_S_construct null not valid"

[driesz]

I'm trying to install Qt (commercial) on Linux (Ubuntu 18.04). The online installer (4.1.0/Linux/x86_64, downloaded today) starts, attempts to verify my credentials and core dumps with the message:

Excpetion thrown:  basic_string::_S_construct null not valid

The same thing happens on Ubuntu 16.04. I'm working with the same machines that I've used successfully with Qt in the past.

As a workaround I downloaded an older Qt online installer (3.2.3) and used it successfully to install qtcreator. The MaintenanceTool and qtcreator executables it installs both fail with the same message.

Can anyone help me find a solution?

Thanks,
Dave Riesz

@driesz Did you search in Qt bug tracker whether it is a reported issue?

@jsulm bugreports.qt.io returned nothing similar to what I'm seeing. I'm not so sure it's a Qt bug. I've got MaintenanceTool running fine on another Ubuntu 18.04 machine.
