Try to understand Debug output. Where can i check meanings?

Ich Openshot Crashes at export (Web-Vimeo-HD) i get Output in the Terminal like

[mp3 @ 0x14eaec60] max_analyze_duration reached

and

[mp3 @ 0x14eaec60] max_analyze_duration reached

...

Is there some Wiki/PDF/... where i can check what it means?
For example what means the 0x14eaec60?
Is this the Clip at the time 0x14eaec60 in ms or ns or something else?
So perhaps i find the problem-clip and disable sound or something like that.

Or

The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
