Konqueror crashes when using zip:/ kioslave with sigegv 11.

Binary package hint: konqueror

Konqueror crashes when trying to open a zip file using the zip:/path/zipfile kioslave. It happens when the file has some '[' ']' characters. It happens in the 6.10 beta branch of Kubuntu.

Way to reproduce it:
*) Open a Konqueror.
*) Write on the address "zip:/path_to_the_zip_file/name_of_the_zip_[.zip" and make sure that there's a zip file with that name and path.
*) If you rename the zip file without the '[' character, then it works and you can browse the file as if it is a directory.

As I mentioned it exits with the 11 signal (SIGEGV) and this traceback:

---------------END TRACEBACK------------------------------------------

Additional notes:
*) The same happens if the character is not a '[' but one of this list ']', '"', '<', '>'.
*) I also tried the '@', '¨', '¡', 'á' characters and they didn't make konqueror crash.
