Description of problem: Provider for Google Calendar bundled with thunderbird-lightning package is incompatible with Thunderbird 8.0 Version-Release number of selected component (if applicable): thunderbird-8.0-2.fc16.x86_64 thunderbird-lightning-1.0-1.fc16.x86_64 How reproducible: Every time Steps to Reproduce: 1. Update thunderbird and thunderbird-lightning 2. Open Thunderbird Add-ons manager /Extensions 3. Actual results: "Provider for Google Calendar is incompatible with Thunderbird 8.0 Provider for Google Calendar 0.9 pre (disabled)" Expected results: Provider for Google Calendar should be enabled or able to be enabled. Additional info: thunderbird-lightning-1.0-1.fc16.x86_64 seems to ship Provider 0.9pre. https://addons.mozilla.org/en-US/thunderbird/addon/provider-for-google-calendar/versions/ suggests that version 0.9 is needed for compatibility with thunderbird 8.0.
I cannot reproduce this on my machine with (same, but 32-bit): thunderbird-8.0-2.fc16.i686 thunderbird-lightning-1.0-1.fc16.i686 The install.rdf file for 0.9pre lists compatibility with all 8.* versions. Are you sure you don't have any manual installs of these around? Any 32-bit versions? You restarted thunderbird after any updates?
Yes, I did restart thunderbird. I couldn't find a manual install of this extension in my account. I confirmed that there is no problem when using a clean account or new profile. I removed my other manually installed extensions - problem persists. Renaming the file extensions.sqlite to extensions.sqlite.off fixed the problem.
Thanks for posting the workaround.
