sthen@, do you think this might be worth a pkg-readme? Scott was able to trace the issue back to memory limits but other users might not know how to deal with this. Scott, I believe you use the .desktop file to launch FreeCAD, correct? If so, you will probably want to make a copy under ~/.local/share/applications that launches a wrapper script, as sthen@ suggests.
