**System:**
- opencv 3.1
- mint 17.2
- python 2.7.6
- pycharm 2016.2 prof
- ipython 5.0
**Error message taken from ipython:**
OpenCV Error: Assertion failed (0 <= _rowRange.start && _rowRange.start <= _rowRange.end && _rowRange.end <= m.rows) in Mat, file /home/georg/ocv31/modules/core/src/matrix.cpp, line 477

what(): /home/georg/ocv31/modules/core/src/matrix.cpp:477: error: (-215) 0 <= _rowRange.start && _rowRange.start <= _rowRange.end && _rowRange.end <= m.rows in function Mat
Warning: Program '/usr/local/bin/ipython' crashed.
In [1]: import cv2
In [2]: import numpy as np
In [3]: a = np.zeros((31,20), np.uint8)
In [4]: b = cv2.Canny(a, 60, 300, L2gradient=True)
After this lines, ipython crashes with the messages above. It will not crash after setting L2gradient to False, or if changing the shape (e.g. 30,20).
The same happens with pycharm.
I have not had this message with opencv 3.0.
Can somebody help me?
09.08.2016:
Now I have installed ocv 2.4.13. Everything is working well.
BTW: The Message **Corrupt JPEG data: 2 extraneous bytes before marker 0x#** during reading the video frames, is also disappeared (Logitech c270).
