I don't do forums so I thought I'd try yours. I am stumped and am looking for help. I am running Ubuntu 10.04 and have enjoyed Calibre for years. Recently I updated calibre and I'm not sure what happened but now when I open Calibre I get the following message:

Traceback (most recent call last):
File "/usr/lib/calibre/calibre/gui2/library.py", line 631, in headerData
return QVariant(self.headers[self.column_map[section]])
KeyError: 'ondevice'

I have removed and reinstalled Calibre both via the terminal and Synaptic and rebooted with the same results.
I used:
sudo python /usr/bin/calibre-uninstall
sudo rm -fr /opt/calibre
sudo reboot

With the same results I cannot figure out what is wrong I dual boot with Windows 7 and it works fine there but I prefer not to use Windows 7. I thought that would completely remove Calibre via terminal then I did a new install via Synaptic, or is it a OS problem? I am totally lost.
Please help.
