Using the replace option from the context menu in a textedit field in konqueror doesn't work for a Regular Expression search.
Replacing content with the regex "\[http://[^ ]+ ([^\]]+)\]" that is expected to match a url entry in Mediawiki's syntax (e.g. "[http://google.com Google Website]") results in inserting the string "\1" instead of doing the proper replacement (e.g. "Google Website"), though "Use placeholder" (or whatever the English option is, German version over here) is checked, and the placeholder is selected by "Insert placeholder" (or whatever... see above).
This option works in kate, so I file this report against konqueror, where this is reproduceable for me. I remember having this problem for some time now, so this is nothing that came with 3.5.5.
