Subject: gtktextview: Fixed arrow key crash.
X-Git-Tag: archive/raspbian/4.4.1+ds1-2+rpi1^2~18^2^2~21

gtktextview: Fixed arrow key crash.

When pressing the keyboard arrows to move around when the insertion point is
hidden, it causes an assertion error in blink_cb.

Insertion point blinks should only be scheduled when blinking is enabled and the
insertion point is visible.

Closes #4275
