Assuming I don't have a busted build, this is a P1 regression. Open fast/xsl/xslt-missing-namespace-in-xslt.xml and click somewhere and choose "inspect element". I then tried to disclose the "Other" section of the right hand column in the inspector, but I think Safari had already hung by then. 59798 2 eric 2007-10-29 11:06:41 -0700 I saw this in the console of at least one Safari instance: 2007-10-29 12:30:42.904 Safari[5434:613] *** Exception received from DOM API: 8 dom Mon Oct 29 12:39:09 HackTop.local Safari[5434] <Error>: CGAffineTransformInvert: singular matrix.
