[CMake] missing file causes an empty solution

[Andrea Galeazzi]

I found one possible VS2008 bug, just following these steps:
1 - Create a VS2008 solution based on a correct CMakeLists.txt
2 - Open the solution and edit CMakeLists.txt  adding a non-existent 
file into the list of sources.
3 - Build the solution (F7 is my shortcut)
4 - It appears  the message: << The solution 'name' has been modified 
outside the environment. Press Reload to load the update solution from disk.
Press Ignore to ignore the external changes. The changes will be used 
the next time you open the solution. >>
5 - If you press Reload, VS2008 will open a solution containing none 
projects, so it's not possible to recovery the situation. The only way 
is to fix the CMakeLists.txt by an external editor and generate the 
solution again by using cmake-gui or cmake command line.
Is it an already known bug? Should I open a bug in the bug-lists?
Cheers
