Now, we don't initialise it anymore if the first target is a URL!

And here, we use it:

See http://ci.apache.org/builders/svn-slik-w2k3-x64-ra/builds/1628/steps/Test%20fsfs%2Bserf/logs/faillog
Now we could crash. But in the failing test *pcommon happens to
point to some string from a previous invocation of this function.
We ended up using that value, which happened to be a dirent,
causing the assertion failure. Fixed in r1066143.
