Public bug reported:
32-bit KUbuntu 10.04, seeing SEGV's in Konqueror, Firefox, and Chrome.
Stack backtrace gathered from Firefox:
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.3) Gecko/20100423
Ubuntu/10.04 (lucid) Firefox/3.6.3
Happens on multiple video hardware configurations on multiple machines
here.
Note that under Chrome, due to its use of processes, it just displays an
"Aw, snap!" failure page, but the browser keeps going. On FF it bombs
all the way out.
SW version for Cairo components: libcairo2_1.8.10-2ubuntu1_i386.deb,
libcairomm-1.0-1_1.8.0-1build2_i386.deb
