Subject: [PATCH] Related: rhbz#1076264 intermittent a11y crash in calc
http://retrace.fedoraproject.org/faf/reports/338291/
this crash refuses to be captured alive. But seeing as
we sometimes check mpViewShell against NULL and sometimes check
GetViewData against NULL its worth making those checks everytime
for consistency
