StackOverflowException during loading of iStudio


I just reverted code from SVN to the last revision.
So there is no my changes in code.

I build it, starting debug it using F5 combination. After a few moments I got StackOverflowException on line 37 of file iStudio/View/Alert.xaml.cs.

My environment is Windows 7 x64, Visual Studio 2012. This error is not connected with environment. It is logical error. It is easy to resolve but I will get another error about which I have created bug.

What am I do wrong? Is there in SVN last version of code?
