Description
I'm not sure exactly what happened, but I was using Qt Creator (from the Linux web installer) and editing a .pro file in the text editor (removing elements from the SUBDIRS list). Qt Creator may have been automatically rerunning qmake in the background and writing to "6 General Messages". Then the program locked up and crashed:

I don't think the bug is reproducible though (I updated to 6.0.0-beta2 and haven't had luck yet). Seeing that libCppEditor.so is on the stack trace, it might be an interaction between editing QMake files, changing the C++ environment and parsing, and a C++ text editor I may or may not have had open.
