[Bug 113298] kde applications fail due to library problem

[BryanLawrence]

Public bug reported:

I have a version of python in /usr/local.

When /usr/local is mounted during login, a number of applications do not
appear in my taskbar, and fail with bizarre messages when requested from
system settings.

Two that really matter are guidance and the power manager (battery
monitor) (Actually, I think these are the same, but I'm not quite sure).

It appears that while the (some?) kde python applications correctly use
/usr/bin/python, they are nonetheless picking up the python site-library
from /usr/local

Investigating with guidance shows the following error when run from the
command-line

./guidance-power-manager
bnl at sstdlbnl:/usr/bin$ Error in sys.excepthook:
