[ Impact ]

openshot is completely unusable as it will fail to start with the
following error:

Traceback (most recent call last):
  File "/usr/bin/openshot-qt", line 33, in <module>
    sys.exit(load_entry_point('openshot-qt==2.5.1', 'gui_scripts', 'openshot-qt')())
  File "/usr/lib/python3/dist-packages/openshot_qt/launch.py", line 97, in main
    app = OpenShotApp(argv)
  File "/usr/lib/python3/dist-packages/openshot_qt/classes/app.py", line 219, in __init__
    self.window = MainWindow(mode)
  File "/usr/lib/python3/dist-packages/openshot_qt/windows/main_window.py", line 2521, in __init__
    self.timeline = TimelineWebView(self)
  File "/usr/lib/python3/dist-packages/openshot_qt/windows/views/timeline_webview.py", line 3000, in __init__
    self.cache_renderer.setInterval(0.5 * 1000)
TypeError: setInterval(self, int): argument 1 has unexpected type 'float'
     version:INFO Found current version: {"error_rate_stable": 0.25, "trans_rate_stable": 0.01, "error_rate_unstable": 0.05, "openshot_version": "3.1.1", "trans_rate_unstable": 0.001}

[ Test Plan ]

Simple test:
* Execute openshot-qt, which will fail to start if its not fixed.
* With the fixed package, openshot-qt will start and the tutorial will show.

Detailed test:
* Import few videos or images
* right click on the thumbnail
* Click on "Add to timeline"
* the image or the video should now be added to the timeline
* add few such images and videos
* Try playing the timeline

[ Where problems could occur ]

The problem was caused because float is used as some of the arguments
where int is now expected. There can be some more such parts in the code
which I might have missed during my testing. And if any such code is
executed with a float argument then the application might again crash.

[ Other Info ]

 * As mentioned in the patch, part of the patch is from upstream. Similar changes have been done in few more places which I found during testing.
