Running arch linux + gnome 3.26. gnome-shell crashes when PyCharm Community Edition 2017.2 reaches the New/Open project screen. This did not occur before upgrade to 3.26.

To reproduce w/ PyCharm:
1. Launch PyCharm
2. Close automatically opened project
3. Crash


$> gnome-shell --version
GNOME Shell 3.26.1

$> uname -r
4.13.4-1-ARCH

gnome-shell -> journalctl:

gnome-shell[846]: The program 'gnome-shell' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
 (Details: serial 35488 error_code 3 request_code 18 (core protocol) minor_code 0)
 (Note to programmers: normally, X errors are reported asynchronously;
  that is, you will receive the error a while after causing it.
  To debug your program, run it with the GDK_SYNCHRONIZE environment
  variable to change this behavior. You can then get a meaningful
  backtrace from your debugger if you break on the gdk_x_error() function.)
