iceowl-extension 1.0b2 not compatible with icedove 3.0.11

[Gilbert Sullivan <whirlygig@comcast.net>]

I have pure testing systems (no contrib or non-free, no closed source 
software / firmware).

This morning these upgrades (excerpted from the aptitude log)

[UPGRADE] calendar-google-provider 1.0~b1+dfsg2-2 -> 1.0~b2-4
[UPGRADE] calendar-timezones 1.0~b1+dfsg2-2 -> 1.0~b2-4
[UPGRADE] iceowl-extension 1.0~b1+dfsg2-2 -> 1.0~b2-4

were offered and installed.

Now the calendar is no longer available in icedove. And the Add-ons 
dialog from Icedove indicates that iceowl-extension 1.0b2 and provider 
for Google calendar 0.7 are not compatible with icedove 3.0.11.

No kidding?

:-)

I can has my calendar back???

Heh. Seriously, I didn't see this coming, and we depend pretty heavily 
on our calendars. Has anyone heard any news about this?

Thanks,
Gilbert
