Mysterious Progress Dialog Pops Up and Occasionally Crashes OpenFlipper
On a vanilla OpenFlipper-Free build, without ~/.OpenFlipper folder (i.e. no stale settings), when you open the File -> Options dialog and wait for 3-5 seconds an unlabeled progress dialog pops up (see screen shot). When you close it by clicking the "Cancel" button on roughly 1 out of 3 instances OpenFlipper crashes.
