plugin crashes 8.0.1 but works on 8.0.0

I get a Qt Creator crash with the "ROS plugin" at: https://github.com/ros-industrial/ros_qtc_plugin/releases/download/8.0/ROSProjectManager-8.0-Linux-x86_64.zip when creating a new project (Ctrl+Shit+N). The debug logs show that it is somehow related to loading the icon.

This only happens on 8.0.1 but not on 8.0.0. Minor updates are supposed to be ABI compatible, right?

WORKING VERSION (8.0.0)

1. download and extract https://download.qt.io/official_releases/qtcreator/8.0/8.0.0/installer_source/linux_x64/qtcreator.7z to "qtcreator800"
2. extract ROSProjectManager-8.0-Linux-x86_64.zip into "qtcreator800"
3. run "bin/qtcreator", press Ctrl+Shift+N, see popup with ROS project option

BROKEN VERSION (8.0.1)

1. download and extract https://download.qt.io/official_releases/qtcreator/8.0/8.0.1/installer_source/linux_x64/qtcreator.7z to "qtcreator801"
