Firefox dlopen's and dlclose's libcups - after dlclose'ing libcups the function pointers used by libcups for SSL support point to invalid addresses and you get a crash.  This also affects Thunderbird and presumably any other Mozilla.org application that prints.

STR #3605 is a placeholder bug for changes we'll need to make once GNU TLS and OpenSSL add native threading support to their respective libraries:

In the meantime you can back out the changes added in STR #3461 to revert to the previous (and apparently unsafe) usage of OpenSSL from multiple threads.
