Sample program to demonstrate this issue.

Dear Development Team,

on my current Arch Linux installation I've found an issue while I was working with System.Diagnostics.Process class.
When I try to use the method Process.MainWindowTitle in order to get the window title of processes, it only returns "null".

I have added small sample code in order to better repdroduce this issue.

Since I've googled around a bit, I figured out, that this issue seems to be alread reported in another Bug tracker in 2009 ( http://lists.ximian.com/pipermail/mono-bugs/2009-June/090036.html ), but I was not able to find this issue in Xamarin Bug Tracker.

I also moved my compiled .exe file to a Windows machine and when I run this file there, it works well and I get window titles from each graphical program I run.

Yours Sincerely

This is expected, the concept of the MainWindowTitle which is prevalent on Windows does not exist on Unix, as there is no way to reliably determine this value.
