found 651636 1.8.1-3.4 thanks Hi,
I've tested the new builds on mipsel, but when JavaScript is enabled things are still unstable. The attached crashes from GtkLauncher are easily reproducible by starting the SunSpider benchmark and refreshing after a few seconds: http://www.webkit.org/perf/sunspider-0.9.1/sunspider-0.9.1/driver.html The crash is in a different component now (JSC instead of JIT?) -- System Information: Debian Release: 7.0 APT prefers testing APT policy: (500, 'testing') Architecture: mipsel (mips64) Kernel: Linux 3.2.0-4-loongson-2f Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/mksh-static Versions of packages libwebkitgtk-1.0-0 depends on: ii libatk1.0-0 2.4.0-2 ii libc6 2.13-37 ii libcairo2 1.12.2-2 ii libdbus-1-3 1.6.8-1 ii libdbus-glib-1-2 0.100-1 ii libenchant1c2a 1.6.0-7 ii libfontconfig1 2.9.0-7.1 ii libfreetype6 2.4.9-1.1 ii libgail18 2.24.10-2 ii libgcc1 1:4.7.2-5 ii libgdk-pixbuf2.0-0 2.26.1-1 ii libgeoclue0 0.12.0-4 ii libgl1-mesa-glx [libgl1] 8.0.5-3 ii libglib2.0-0 2.33.12+really2.32.4-3 ii libgstreamer-plugins-base0.10-0 0.10.36-1 ii libgstreamer0.10-0 0.10.36-1.1 ii libgtk2.0-0 2.24.10-2 ii libicu48 4.8.1.1-10 ii libjavascriptcoregtk-1.0-0 1.8.1-3.4 ii libjpeg8 8d-1 ii libpango1.0-0 1.30.0-1 ii libpng12-0 1.2.49-1 ii libsoup2.4-1 2.38.1-2 ii libsqlite3-0 3.7.13-1 ii libstdc++6 4.7.2-5 ii libwebkitgtk-1.0-common 1.8.1-3.4 ii libx11-6 2:1.5.0-1 ii libxml2 2.8.0+dfsg1-7 ii libxrender1 1:0.9.7-1 ii libxslt1.1 1.1.26-14 ii libxt6 1:1.1.3-1 ii zlib1g 1:1.2.7.dfsg-13 Versions of packages libwebkitgtk-1.0-0 recommends: ii gstreamer0.10-ffmpeg 0.10.13-5 ii gstreamer0.10-plugins-bad 0.10.23-7.1 ii gstreamer0.10-plugins-base 0.10.36-1 ii gstreamer0.10-plugins-good 0.10.31-3+nmu1 libwebkitgtk-1.0-0 suggests no packages. -- no debconf information
