Well, the number of crashes is decreasing, that is a good signal :-)
Following my last post about bugs fixed in Plasma NM, here is the list of bugs fixed between 4.6.3 release date (May 6th) and 4.6.4 release date (June 10th):
. Fix NM version number check.
. Always shows the "Create connection" button in the interface added notification for modem interfaces. Until now it was only shown when there was no modem connection.
275163: Fix changing adapter display type disables networking system
275159: Disables "Show More" button instead of hidding it if there is no wireless interface available.
275160: Defaults to wired tab in ManageConnectionWidgets if wireless is disabled.
274702 275161: Try to prevent opening kwallet when there is no secret to retrieve.
274797: Set right widget's width to fixed size to prevent unneeded graphical layout resizes.
146159 182984: Import VPN connections from configuration files. Only VPNC is implemented so far, but the hooks for other VPN types are in place now.
. Fix initial default route icon's state when starting kded module and a connection is already active.
274860: Change networkmanagement_shell into a singleton to prevent calling the edit connection dialog multiple times.
274859: Disable "Low signal strength" notification by default and increase the interval between "Low signal strenght" notifications to 5 minutes.
274846: Backport fix for disconnecting auto-connect connections when compiled against Solid < 4.7.0.
. Fix some issues when entering wireless channel manually instead of using the spinbox buttons.
. Add text in main window to warn when using Plasma NM with wrong NM version.

273894: Prevent crashes when closing kcmshell too fast after closing the connection editor.
. Fix two crashes when editing IPv4 config.

266268: Try to adjust plasmoid size automatically.
273265: Fix crash on editing connections in KCM module.
. Update main CMakeLists.txt file to indicate that now we need at least NetworkManager-0.8.1. That is because of the IPv6 implementation, which first appeared in 0.8.1.
. Fix UUID check for DUN and NAP services in networkmanagement_configshell which prevented adding new Bluetooth connections.
272942: Change the automatic launching of Mobile Connection Wizard into a notification.
157384: Allow automatically set connection's BSSID to the BSSID of the AP selected in scanwidget.

. Several memory leak fixes.
