ERROR : Invalid sort order in properties

[QFabian]

Hi, this is a non expected behavior: 

i have  a bookmark that works fine, but one visualization start to fail showing this :

I checked the order properties and everything is set by default.

I even recreate the visualization, with the same results.

But, i made a copy of the visualization, and start to works fine again, even using the bookmark., and the original still failing.
