[basex-talk] Duplicate declaration of static variable

Hi,

when loading my RESTXQ app I get this:

Stopped at C:/Users/dev/.jetty/webapps/basex/fwdev/lib/account.xqm, 20/18: [XQST0049] Duplicate declaration of static variable $acc:last-visited.

dev@mambo ~/.jetty/webapps/basex $ grep -R --include="*.*" "$acc:last-visited" . ./fwdev/lib/account.xqm:declare variable $acc:last-visited as xs:dateTime? external := ();

As it seems, there is no other declaration of the variable in the whole project. What could that be?
