thunderbird-lightning and sunbird: libcalbasecomps.so: undefined symbol: icaltime_compare_date_only_tz

[John Thompson]

Lightning (1.0-0.6.20090715hg.fc11) and sunbird
(1.0-0.5.20090715hg.fc11) had been working well for me recently on
Fedora-11 x86_64 but this morning I am greeted with the error message:

[john at lancre ~]$ thunderbird
Registering Enigmail account manager extension.
Enigmail account manager extension registered.
/usr/lib64/thunderbird-3.0b3/thunderbird-bin: symbol lookup error:
/usr/lib64/thunderbird-3.0b3/extensions/{e2fda1a4-762b-4020-b5ad-a41df1933103}/components/libcalbasecomps.so:
undefined symbol: icaltime_compare_date_only_tz

I have tried reverting to to early versions of each but the error persists.

Software changes since the last time lightning/sunbird worked properly are:
