[Joe Ma <hotarunso31@gmail.com>]

Package: kate

Version: 4:16.08.3-1

Dear Maintainers,

As the subject mentioned, kate freeze when right-click the open/save file dialog.

-- System Information:

Kernel version: 4.18.0-0.bpo.1-amd64

Qt version: 5.7.1

KDE Plasma Version: 5.8.6

KDE Frameworks Version: 5.28.0

Step to reproduce:

1) Open new file in kate (File>Open)

2) Right-click in the file dialog

3) Kate and the screen freeze

I can only move the mouse pointer and other thing freeze

Run `killall kate` solve the problem.

Here is the related line in .xsession-errors after kate launched:
