Creator still crashes when playing around with add/remove build configurations

There was a previous issue (http://bugreports.qt.nokia.com/browse/QTCREATORBUG-1035) concerning the removal of build configurations which was fixed. However, I can still make Creator crash with the following steps:

1) Create a GUI project and set up one target (for example, Qt in PATH).
2) Go to project settings. There should be 2 build configurations: Debug and Release.
3) Remove, for example, the Release configuration.
4) Add a new configuration Using Qt Version... (Please note that this new configuration will be the selected one.)
5) Switch to the original Debug configuration.
6) Click remove.
Result: Creator crashes.

Obs.: Apparently Creator doesn't notice that the newly added configuration is now the current one selected. As a consequence you can see on run/debug/build panel that the original configuration is still selected (it was not updated).
