Description

Sometimes (but often enough to be very annoying), Qt Creator crashes when I click somewhere in the edit view as a tooltip is displayed. The tooltips can be, for example, those displayed when you hover a function to see the prototype, or a variable to see its declaration.

Here are the logs :
