ApplyLUT error

I've just noticed astrange behavior when using the Apply LUT effect.
When I drag it onto the Effects Stack widget initially it does nothing, after a second click on the widget the effect is added.
Then, when selecting different LUTs (from the ones in the dropdown menu, it applies them, but after trying some of them, an error message shows (attached). After that, it stops working...

Adding on that. 
1. It's not "after a second click" is just waiting a few seconds after the drag and drop operation.
The strange thing is that in the mean time (after the "drop"), the cursor keeps showing the effects attached to the cursor (screen capture attached below).

2. Every time the clip with the effect is deselected and selected again, there is a waiting time before the stack shows the effect again.

...I don't know if it's searching for/scanning some directories in looking for LUT files or something, but that's the impression I get.
