Sublime Text 2 Ctrl+P doesn't work

Question

Why Sublime Text 2 Ctrl+P doesn't work on some projects while it works on other projects?

Thanks for skuroda's tips, the log in console after hitting ctrl+p is as folows:

command: show_overlay {"overlay": "goto", "show_files": true}
Unable to auto detect encoding, using fallback encoding Western (Windows 1252)

It's hard to offer any additional help without more information. With that being said, try opening on the console ctrl+backtick or View -> Show Console. In there enter sublime.log_commands(True). Every time you hit ctrl+p, it should print something like command: show_overlay {"overlay": "goto", "show_files": true} . If it doesn't please specify what it does say. In addition, you can verify the input ST is receiving by entering sublime.log_input(True) in the console. This should always return something like key evt: control+p.

Hopefully with those two commands you can provide some additional information. I'll edit my answer appropriately if/when you update.

Edit:

It looks like a plugin is causing issues. I'm guessing it's sublime-gbk, but I'm just guessing. You can try creating an issue on the developer's page and hope it gets addressed. The only thing I could advise is disabling the plugin. You could try modifying the plugin also. This may break something, but in def gbk2utf8(view):, you can do something like

if view is None:
    return

before the try except block. Of course, aligning the spacing as necessary so it's valid Python.
