Blank deck overview after invoking series of API calls

[NSBum]

After invoking a series of calls in a script, the Anki deck overview GUI is completely blank and the application has to be restarted in order to restore the view. The specific actions that are my script invokes are guiDeckReview, getCollectionStatsHTML and guiDeckBrowser. It always concludes with guiDeckBrowser which should, in theory, leave the GUI in the normal resting space; but it's always blank.

Behaviour noted with at least Anki 2.1.41 and 2.1.43, but I think it was present < 2.1.41.
