FileChooser crashes (Win10 64bit) if any file in_use on the target path

[3col]

Versions

• Python: 3.6.3.amd64
• OS: Win10 64bit
• Kivy: 1.10.0
• Kivy installation method: pip install / PyCharm

Description

For example on Kivy Showcase in \data\screens\filechoosers.kv file the FileChooser: have to set the "show_hidden: True". Otherwise FileChooser widget crashes (tested on Windows 10 64-bit), if any file is in_use on the target path. E.g. Win10 "C:\" always contains in_use (system) files; also any other in_use ~tempfile or logfile will cause same error.

@3col can confirm, this is still an issue. Can I ask how you are finding those logs? My instance doesn't raise an exceptions...

[JamesYangLim]

I am getting the same problem as well

[stevewells20]

I am confirming as well, on a VirtualBox instance of Win10 64bit. Can you share how to find those logs, @3col? I can only seem to get the one-line generic error message, "Failed to execute script".

@Julian-O This issue can be marked closed.

@stevewells20 @JamesYangLim @irbigturtle @3col: Are you still experiencing this issue on Kivy 2.2.1 with the latest dependencies?
