I was hoping that you would find some "EACCES (Permission denied)" that
would explain why the program works better when run as root.
A SIGSEGV (segmentation violation) is usually some kind of bug. It is
possible to set the limit of a core dump size with something like "ulimit
-c 500M" and that generated core file might be usable to find the bug,
but that would only be usable if you had access to the source code of the
application.
In lack of source you might have to resort to the simple problem fixing
routine well known to all users of commercial OS and applications:
1) restart
2) reinstall
3) upgrade
However, as acrobat reader are not expected to come with any new version
for Linux you might instead want to try to downgrade.
