First Time Wizard fails when there is no internet connection

Hello

System does not matter, was able to reproduce on XP as well as on xubuntu.

When there is no internet connection while running the first time wizard, the exception dialog opens with a traceback [1]. If you close the exception dialog, openlp will crash/close. There is no way around this, next time you run openlp the wizard starts again. The only way to pass this is to create and set the "has run wizard" to true.

Cheers
