I revisited this issue tonight and after an unnecessary excursion into the land of bleeding xorg, discovered that other user accounts on the same machine don't have the problem. deleted all kwin related conf files in ~/.kde/share/config/ fixes and now no crash.
Tried to comment same on upstream bug but can't login to fd.org bugzilla. -- Xorg crashed with SIGSEGV in _swrast_copy_teximage2d [i855GM] https://bugs.launchpad.net/bugs/287485 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
