Description of problem:
Tried to install a piece of software.  The gnome-software application crashed immediately.  This is 100% reproducible.  I have not idea why the GNOME Software Manager keeps crashing on installation, however.  It used to work before the latest two groups of updates, however.  Now it does not work at all.

Version-Release number of selected component:
gnome-software-3.10.0-1.fc20
