www-client/firefox-bin-3.5.6 adds the file: /etc/env.d/71firefox-bin This file sets LDPATH="/opt/firefox" This in turn means that /opt/firefox/libnspr4.so is picked up by ldconfig before the one in /usr/lib/libnspr4.so, which breaks pidgin (and presumably other apps that rely upon libnspr4.so) Reproducible: Always Steps to Reproduce: 1. emerge firefox-bin-3.5.6 and pidgin 2. run ldconfig to update ld.so.cache 3. attempt to start pidgin Actual Results: pidgin crashes with "Aborted" (strace reveals it crashes just after reading /opt/firefox/libnspr4.so) Expected Results: pidgin loads normally running: export LD_LIBRARY_PATH=/usr/lib before running pidgin allows it to start. 518 20:08 $ strings /etc/ld.so.cache | grep libnspr libnspr4.so.8 /usr/lib/libnspr4.so.8 libnspr4.so

Mixing stable/testing is not supported by mozilla products in gentoo, please either use stable nss/nspr with stable firefox-bin or upgrade to firefox-bin testing.
Moving nss and nspr back to stable versions allows pidgin to be started.
