No, however you are also using a very old version (0.9.9). Please retest
against the latest version. If you are still encountering this after testing
against the latest, feel free to reopen this issue:
http://guacamole.apache.org/faq/#test-against-latest-version
As an aside, if you've recently upgraded guacamole-server or FreeRDP, that
could easily cause a segfault within one of the FreeRDP plugins built by
guacamole-server like {{guacdr.so}}. I suggest making sure that:
# {{guacdr.so}} and all other FreeRDP plugins built by guacamole-server are
actually the result of your latest build of guacamole-server, not an older
installation.
# If FreeRDP has been updated, rerun {{./configure}}, rebuild, and re-install
guacamole-server to make sure it builds against the version you have installed.
Even if the version number of FreeRDP appears to be essentially the same,
different versions of FreeRDP cannot be relied upon to be binary compatible.
