Version: 1.11.3 (using 4.2.3 (KDE 4.2.3) "release 120", KDE:KDE4:Factory:Desktop / openSUSE_11.1) Compiler: gcc OS: Linux (i686) release 2.6.27.21-0.1-default I received an email with the following link: http://integrals.wolfram.com/index.jsp?expr=x+/+sqrt(a+-2bx)&random=false However only the part http://integrals.wolfram.com/index.jsp?expr=x+/+sqrt was displayed in blue and opened in konqueror with right click -> address open.

See also bug 81281 and duplicates, also there's another bug that I can't find quoting some URLs with '[]' characters. Dear me, are there any of the millions of available Unicode characters that are *not* going to appear in a URL somewhere? :-)
