Exception in thread: TypeError: 'NoneType' object is not subscriptable

[Linus Hoppe]

Reported in https://answers.launchpad.net/pyneighborhood/+question/170801:

I am using Ubuntu 11.04, I can browse Windows shares using Gigolo and copy files from my fileserver running Server 2008.
Installed 0.5.1 using Synaptic ( the repository is still not updated), and could not browse Windows share ( file manager is Thunar)
Updated to 0.5.4, still cannot browse shares, the error is consistent after rebooting.
When I enter the URL, IP and share name, I get a generic error: TypeError: 'NoneType' object is not subscriptable

I need the Output of the following command to fix this bug, because i never used Windows Server 2008 at Home ;-)
nmblookup -A ipofyourserver

Please fix your /etc/samba/smb.conf, "testparm" is your friend!

[ed (ed90210)]

Testparm may be my friend, but what am I looking for as the problem - what needs to be fixed ? I was able to create a permanent mount of a remote Windows share ( I edited fstab and the mount is present after reboot). If there was a problem with smb.conf, wouldn't that have showed up when I tried to mount the Windows share?

[Betz Stefan (encbladexp)]

Testparm checks your smb.conf for syntax and context errors, and these should be fixed before we can take a look at your Problem. If you add a host or share to pyNeighborhood, we make a call to nmblookup (a tool for browsing your network) to retrieve host related informations like workgroup and so on

Sorry about the delay, old Xubuntu PC died, set up new PC with Xubuntu 11.04
