It should match both strings. I tried removing portions of the regexp to see which parts are failing but was then unable to reproduce the bug, so the complexity of the regexp may be part of the issue. This bug also occurs in Safari 3.2.1. 111939 1 28207 barryferg+webkit 2009-03-02 17:31:09 -0800 Created attachment 28207 Test case 112001 2 ap 2009-03-03 08:50:56 -0800 See also: bug 24166, bug 18327, bug 21485.
