Users of ubuntu natty are experiencing a sigsegv of libwebkitgtk-1.0-0 in WTF::OSAllocator::reserveAndCommit() on amd64 platforms.
The original bug report was made here:
a backtrace kan be found here:
and a valgrind log here:
several people can reproduce this bug. F.ex by starting up gwibber-accounts and trying to add a new twitter account. Or by using the ubiquity installer.
I think this might be a dupe. CCing Xan who should definitely know.
The trace is different, but it definitely looks like bug 42756. To double check enable overcommit and see if it stops happening (echo 1 > /proc/sys/vm/overcommit).
echo 1 > /proc/sys/vm/overcommit_memory
does fix the problem!
Thanks for reporting this issue! Please refer to the earlier issue for updates.
