question about warning on stderr

[incoming-gnucash at sabot.com]

I've been running gnucash on my Xubuntu precise machine for a few
weeks now, and have (I think) successfully switched myself over from
Quicken.  I've accumulated a few questions along the way that I can't
answer for myself, but I think it is best to trickle them in one at a
time, so I'll start with this:

I'm running what I think is the current version, installed from the
getdeb repo into my Xubuntu precise system:

   $ gnucash --version
   GnuCash 2.6.3
   This copy was built from rev 4e4a032+ on 2014-04-08.

I have been invoking it at the shell, and while the program always
behaves fine, there are always warnings being printed out the shell.
I'm wondering if these warnings indicate a problem I need to fix in my
installation, or if instead they are pretty normal, and I should
probably just invoking gnucash by picking it from the application menu
or setting up a desktop icon so that this output automatically goes to
/dev/nul instead.

For example, every time I run gnucash I see this emitted
around startup time:

   Traceback (most recent call last):
     File "/usr/share/gnucash/python/init.py", line 3, in <module>
       from gnucash import *
   ImportError: No module named gnucash
   Found Finance::Quote version 1.17

Usually that is all, but on occasion (I think when I do something
interesting with reports or qif importing) there are others, such as

   ;;; WARNING (gnc:make-report-anchor: faf410e8f8da481fbc09e4763da40bcc  No such option:  Display Use Stacked Lines)

or

   Backtrace:

Thanks for your help.
