Not sure why this got broken but it used to work:

1. Log into your server of choice (I always use FTP)
2. Select 2 files
3. Right-click and choose "Copy URL" and then either "FTP URL" or "HTTP URL" (alternately, select 2 files and from the Edit menu choose "Copy URL" and then either "FTP URL" or "HTTP URL"). Observe that 2 URLs are listed in the sub-menu.

Expected behavior: 2 URLs are copied to the clipboard
Observed Behavior: Only the first URL is copied to the clipboard

The order in which the items are selected doesn't change the misbehavior. Nor does changing the number of selected items (tried it with 2, 4, and 10 items, same misbehavior observed).

Observed with Version 6.2.0 (25806) - not sure why but Trac doesn't list this version.
