[QGIS-Developer] VirtualXPath noise?

[Richard Duivenvoorde]

When starting QGIS from cli I have a lot of lines with 

'VirtualXPath'	[XML Path Language - XPath]

Eg:

$ qgis
	- 'VirtualXPath'	[XML Path Language - XPath]
	- 'VirtualXPath'	[XML Path Language - XPath]
<string>:1: DeprecationWarning: setapi() is deprecated
	- 'VirtualXPath'	[XML Path Language - XPath]

anybody aware where that comes from, and if it is easy to silence?
 (I grepped my binary dir, but .. apparently binary :-) )

Regards,
