Item2507: Some links with full-colons don't render at all

Here is some verbatim TML with a URL presented three different ways, where only the first form renders properly via the view script:

These three forms are now repeated below, without verbatim, and the expected behaviour is that the last two forms should be clickable links like the first - but instead nothing (ie. only one clickable link - the first - instead of three):

Reproduced in:

• 1.0.7 foswiki.org (just viewing this task should reproduce the fault)
• 1.0.8 production wiki:
  
• Release01x00 r5795 svn installed:
  
• trunk r5795 svn installed:
  

It seems that this has something to do with special handling of the full-colon in the URL. Interwiki plugin?

• Problem persists with InterwikiPlugin disabled

While I don't see the last two links here using Firefox 3.5.x at all (as noted above), I actually do see them (albeit w/o the ':') when looking at the page via the RSS feed using Thunderbird 2.x.

Encoding subsequent colons (i.e., those not belonging to the format specification) doesn't help, either ('%3A' / ':'). But apart from that--shouldn't the third form become an inline image w/o link?

The problem is that the link is not to an image, it's a page about an image (contains HTML).

Added feature proposal that bracketed links are not transformed into images: Development.ChangeImageLinkBehaviour

Lowered to Normal; this is not a new or simple issue, and probably shouldn't block a patch release.

This bug has been fixed in Item11189, which in fact was a duplicate of this bug.

Closing.

Also, this bug triggers a very strange behaviour of ImagePlugin, but this deserves a dedicated bug report, which is Item11333.
