Unity crashes under certain conditions before showing Wizard

Hiho.

THANK you for working on a Unity Editor for Linux!

What happened:
After an unrelated crash I started Unity from the command line while the current directory was {Project}/Temp of the project that just crashed.
But Unity consistently crashed each time immediately with:

Code (csharp):

1.  
2. terminate called after throwing an instance of 'std::logic_error'
3.   what():  basic_string::_S_construct null not valid
4.  
5. [1]    Abort                         /opt/Unity/Editor/Unity (core dumped)
6.  

Only after I moved out of the Temp directory did Unity start up and show the project wizard.

=> maybe the Temp directory got already deleted and was "invalid"/a zombie (the directory was empty). Or maybe Unity tried to remove the old Temp on startup, which was denied because I was still using it.
