When pidgin starts it tries to load libsipe.so but fails. This means that pidgin can no longer be used to communicate with Microsoft Office Communicator. Starting pidgin with debug shows: (15:43:19) plugins: probing /usr/lib64/purple-2/libsipe.so (15:43:19) plugins: /usr/lib64/purple-2/libsipe.so is not loadable: undefined symbol: GSS_KRB5_NT_PRINCIPAL_NAME Doing a ldd on libsipe.so and comparing 1.13.1 and 1.13.2 shows 1.13.2 does not have dependencies on libcom_err.so.2 libgssapi_krb5.so.2 libk5crypto.so.3 libkeyutils.so.1 libkrb5.so.3 libkrb5support.so.0 libssl3.so Looking in the config.status shows that LIBS is defined as S["LIBS"]=" -L/usr/lib64 -O2 -pipe -march=native -Wl,-O1 -Wl,--as-needed -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lkeyutils -lresolv -ldl" in 1.13.1 but as S["LIBS"]="" in 1.13.2. So it looks like some configuration changes have broken it. Reproducible: Always Steps to Reproduce: 1.Run pidgin with sipe plugin 2. 3. Actual Results: Microsoft Office Communicator account is no longer working and no longer appears under the list of valid protocols. Expected Results: Microsoft Office Communicator account to work.
