Saving layers not working

[Remco Slijkhuis]

SVMT version 0.2.0, running on Linux (Fedora Core 11).

Saving layers has problems and in the end does does not work:

- Typing a name is sometimes impossible because what has been just typed gets magically and continually selected and then overwritten when typing.
- Pressing 'Save' does not save.
- There are lots of messages on the terminal like:
    qrc:/declarative/FilterPanel.qml:139: TypeError: Result of expression 'loadLayersState' [RangeError: Maximum call stack size exceeded.] is not a function.
  which are then followd by a single
    <Unknown File>:0: RangeError: Maximum call stack size exceeded.

This already happens with one tab. I also tried when having 2 or 3 tabs; same result. Also the numer of constraints selected did not make a difference (same result with 5 as with 1).
