qtcreator segfaults on startup



  • I'm just starting out, and it crashes right out of the gate.

    $ uname -srvmpio
    Linux 3.16.0-4-686-pae #1 SMP Debian 3.16.7-ckt11-1+deb8u6 (2015-11-09) i686 unknown unknown GNU/Linux

    Installed via package manager.

  • Qt Champions 2019

    Hello and welcome!
    You can try to start QtCreator with disabled Welcome plug-in:

    qtcreator -noload Welcome
    

    If it helps you can disable it in "Help/About Plugins...".



  • That seems to help. I'll explore this further when I get a chance. Thanks.
