New submission from Matthias Klose <d...@debian.org>:
[forwarded from https://launchpad.net/bugs/597763]
seen with all version, built with Tcl8.5
To reproduce the bug, use the following class:
class x(object):
TEST = "hello"
THE_MAXIMUM = 55
def __init__(self, a, b):
self.a = 3
self.b = "test"
and set the cursor behind "test". After that use SHIFT + UP (so from 3 to incl.
"test" will be marked) and after that use SHIFT + POS1, which will produce this
exception:
>>> Exception in Tkinter callback
