Description of problem:
Anaconda crashed a moment after start of the installation.

There was default installation of Fedora 26 on FW RAID (mirror). I wanted to delete all partitions and install default Fedora again.

Version-Release number of selected component:
anaconda-26.21.3-1

The following was filed automatically by anaconda:
anaconda 26.21.3-1 exception report
