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@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.
