[Geany] No code that checks if any files are opened.

[Jacek Wolszczak]

Hi
    First of all I'd like to say thank you for geany. It's a really cool 
app without all that useless stuff that would make it "heavy".
    I'd like to report a bug that should be easy to fix. When no files 
are open and I click "run" toolbar icon, I get segmentation fault. It is 
quite reproducible. The solution would be to disable the icon/button 
when the number of opened files equals 0.

   Best regards,
    Jacek
