Description of problem:
Package: NetworkManager-openvpn-gnome-0.9.8.2-3.fc20

When configuring a new VPN connection and selecting a PKCS#12 file, the following process loops (100% thread usage) and then segfaults:
  /usr/bin/nm-connection-editor --show --type vpn

If PKCS#12 file are not supported, those should not be listed as allowed file types by NM Connection Editor, and it should reject incompatible files instead of looping/crashing.

Version-Release number of selected component:
nm-connection-editor-0.9.9.0-7.git20131028.fc20
