paste.debian.net: user should have max 10 chars

How to reproduce:
$ id -un
leandrotoledo

$ dmesg | pastebinit
http://paste.debian.net/

339 page = url_opener.open(website, params) #Send the informations and be redirected to the final page
340 print page.read()
...
<b>Invalid format for name (no special chars, max 10 chars)</b><br>
...

Possible fixes:
1) hard-coding for paste.debian.net (ugly way)
124 if param == 'user':
125 if pastebind[pastebin]['pastebin']['basename'] == 'paste.debian.net':
126 params[paramname] = user[:9]
127 else:
128 params[paramname] = user

2) default user valeu from conf file should override localuser value (ugly too)

3) remove user from paste.debian.net.conf
