Hi Chris, It's reproducible on any version of Firefox that I've tried including the ones distributed with Ubuntu (10.04 through to 12.04) an from 3.5 up to FF12.
I can try and obtain another backtrace from your suggestion, but using the steps to reproduce and the test case it's easy to reproduce.

Download the two JRE's from: http://www.oracle.com/technetwork/java/javase/downloads/index.html 2. Extract both Oracle JRE's: $ bash ./jre-6u31-linux-i586.bin $ tar -xvf jre-7u3-linux-i586.tar.gz $ sudo mv jre1.* /usr/lib/jvm 3. Install the plugins into the alternatives system to switch easily: $ sudo update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /usr/lib/jvm/jre1.6.0_31/lib/i386/libnpjp2.so 1059 $ sudo update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /usr/lib/jvm/jre1.7.0_03/lib/i386/libnpjp2.so 1058 4. Unpack the xslt-crash-reproducer.zip $ unzip xslt-crash-reproducer.zip 5. Open Firefox and check "about:plugins", open file:///path/to/test1.html . Repeat with alternating java plugins using alternatives to reconfiure which plugin is active: sudo update-alternatives --config mozilla-javaplugin.so = backtrace = [Thread 0xa38a7b40 (LWP 2384) exited] nsPluginNativeWindowGtk2: call SetWindow with xid=0x3e00291 --DOMWINDOW == 14 (0x811f4368) [serial = 14] [outer = 0x811e7e58] [url = about:blank] Program received signal SIGSEGV, Segmentation fault. 0xb5fd9fbb in AssertActivityIsLegal () at /tmp/buildd/firefox-12.0+build1/build-tree/mozilla/xpcom/base/nsTraceRefcntImpl.cpp:167 167 /tmp/buildd/firefox-12.0+build1/build-tree/mozilla/xpcom/base/nsTraceRefcntImpl.cpp: No such file or directory.
