--- Comment #1 from Tommaso <tommaso.gamaleri at enostra.it> ---
I tried again and I discovered exactly when it happens: 

1) If I press right-click on a file WHILE it is syncing, then Dolphin crashes

2) If I press right-click AFTER the file has been synced, then Dolphin context
menu opens regularly
