Care to tell me/us what version of Debian you're using?
# Looks like testing/unstable, though, from the version numbers.

Sure looks like a C++ issue.  Either a missing library or a library
with the wrong C++ ABI.  I haven't seen this during development but
that most likely because I get to compile from source ...
# Development is done on Debian GNU/Linux testing (despite the fact
# that EPSON KOWA does not support Debian :-().

Steve, please send a bug report to pipsnews@epkowa.co.jp.
# And a request for debian packages ...
