Question about super()

[Qiang Guo]

Hi, all

I have a question about offlineimap's compatibility with
python-2.6. The logging modules in Python-2.6 is old-styled class, which
means super() cannot be used. This will cause UI malfunctional. BTW, I
am using 6.5.1.2. Is the support form 2.6 dropped with new branch ?
