Qtiplot's config files are installed in /urs/local/qtiplot. However, if this directory is own by root:root and its permissions are drwxr-xr-x, qtiplot can't create the files qtiplotrc.pyc and qtiUtil.pyc inside it for a regular user at launch time. I had to manually modify the permissions of /urs/local/qtiplot to drwxrwxrwx. Reproducible: Always Steps to Reproduce:
I've just committed an improved ebuild to cvs. It installs python files to /usr/lib/python<version>/site-packages and compiles them. This should fix the bug. Please check. Please rm -rf ~/.config/ProIndependent before starting qtiplot for the first time after updating to this new version. If it works, please, close the bug.
Yes, the bug is gone. Thanks very, very much.
