It's like writing web applications that have to work on Internet
Explorer - sometimes you have to make allowances for stupid but
prevalent applications. Unfortunately, in the case of URL abuse, it
happens so often it limits the usefulness of applications that are too
strict about the standard.

It doesn't unless at least KHTMLPart operates in that mode by default,
and I suspect that would defeat the usefulness of the IDN support in
KURL.

How about this: the .protocol control files in $KDEDIR/share/services
could be extended to include a directive specifying that the given
protocol uses non-standard URLs, which KURL would obey and not attempt
to process further. It's a bit like my previous suggestion of hardcoding
a set of protocols that use DNS host names, only a little more sane and
flexible. I'd be happy to come up with a patch to implement it if it
doesn't sound too unreasonable.
