In GIPF 27499, I made a move that resulted in 2 lines of 4 being formed (Jest Phulin 30/04/2016 16:46)
The basic result was this
BBBB
W
B
B
B
B
The game removed the vertical line first, leaving
_BBB
_
_
_
_

I had wanted to remove the horizontal line first, which would have returned more to my stock, while still capturing the white. I believe this is a bug under rule E 3.
Aussi, je suis désolé, je ne parle pas français.
