[opensuse-gnome] Browser alert boxes

Hi, I've been running a mixed version of Factory + 11.4 + 12.1 so far. Today I decided to upgrade to 12.1 proper. After the upgrade, browser javascript alert boxes seem to appear in a KDE-ish flavor (see attachment). Anyone else facing this issue ? With this same chrome browser, on my previous OS (11.4 +12.1 etc.) , the alert boxes were in GNOME-ish flavor. Should I file a bug ? Sankar http://psankar.blogspot.com
