evolution-data-server is being rebased for RHEL 5.2 (see bug #318631), so we'll need to rebuild pidgin against the newer e-d-s libraries at some point.
Go ahead and do it on my behalf when the time comes.
Assigning this to myself.
Actually, I will need to rebuild it anyway due to 311161, so you don't need to do any work here other than verify that the rebuild has happened against the right version of e-d-s.
Product Management wasn't too keen on rebuilding a bunch of desktop packages that weren't on the Approved Component List, so I found a way to preserve the old ABI in libedataserver.so. This was the only library that changed since e-d-s 1.8.0. Devel NACK'ing since a rebuild is no longer necessary.
Development Management has reviewed and declined this request. You may appeal this decision by reopening this request.
