Issue 9201: IDLE: raises Exception TclError in a special case (original) (raw)

[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:
