Error when trying to add an attachment to a ticket

[rohan@…]

Steps:

1. Tried to add an html file attachement. Denied due to "number of external links" exceeded (spam).
2. Zipped the html file and hit "back" to try and add the attachment as a zip file.

The following error appeared:

On which version of Trac did this error occur?

[Rohan]

The problem occured as an end-user of a Trac installation, so I don't know what version it is, but here's the URL of the installation:

​http://code.djangoproject.com/simpleticket

Ok, so this is a 0.10.3 installation.

Likely to be a duplicate of #5061 and finally #4087.
