Inkscape open other session and close it while user copy / paste text area from a layer to another

Inkscape 0.91 r13725 (Linux 63 bits)

How reproduce the bug :
-create a new doc
- create a text area and fill it with some pseudo text
- create a new layer
- select the texte area, copy it
- select new layer in order to past the text area....
And that’s it :

Inkscape opens a message box with two sentences :

"Inkscape has received additional data from the script executed. The script did not return an error, but this may indicate the results will not be as expected."

"No paths where found. Please convert all objects you want to save into paths."

It opens after that a new session of itself, with the text, and close it just after

After that, Inscape loops to the first message box...

Hope it helps...
