ValueError in column.py

[M5klTig3r]

When I started my Anki today, I got this error in front of me:

Error 
An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed. 
If the issue only occurs when add-ons are enabled, please use the Tools>Add-ons menu item to disable some add-ons and restart Anki, repeat until you discover the add-on that is causing the problem. 
When you've discovered the add-on that is causing the problem, please report the issue on the add-ons section of our support site.

ValueError: too many values to unpack (expected 2)

I searched a little bit and found on your add-on website that somebody fixed the issue with these lines:

def _linkHandler(self, url):
if ":" in url:
##(cmd, arg) = url.split(":")
param = url.split(":")
cmd = param[0]
arg = param[1:len(param)-1]
if cmd == "dragColumn":
return columnHandler(self, arg)
elif cmd == "optsColumn":
return columnOptions(self, arg)
return lastHandler(self, url)

I changed it and it works.
Still, I think that it would be a nice thing if you'd changed it right away, cause not many can do this!

If you have any questions, please contact me.

Best regards,
