Related Forum thread: http://forums.gentoo.org/viewtopic-t-565653.html Due to some wierd interaction, kded from kdelibs-3.5.7 (responsible for plugin-loading, e.g. kwallet, kcookiejar) crashes with openssl-0.9.8x: [...] kdecore (KLibLoader): Loading the next library global with flag 257. kdecore (KLibLoader): WARNING: KLibrary: /usr/lib/libcrypto.so.0.9.8: undefined symbol: PKCS7_content_free kdecore (KLibLoader): Loading the next library global with flag 257.

Reproducible: Always Steps to Reproduce: Merge KDE-3.5.7 and openssl-0.9.8x, try to access secure IMAP (kmail) or secure web server (https). Downgrading to openssl-0.9.7i solved the issue.

I've been getting these warnings for ages without any noticeable effect. https and everything else ssl-related works just fine Are you on x86 and missed the warning, maybe? ewarn "Due to the way openssl is architected, you cannot" ewarn "switch between optimized versions without breaking" ewarn "ABI. The default i686 0.9.8 ABI was an unoptimized" ewarn "version with horrible performance. This version uses" ewarn "the optimized ABI. If you experience segfaults when" ewarn "using ssl apps (like openssh), just re-emerge the" ewarn "offending package." Thus, please try re-emerging kdelibs and let us know if that helped. (I'm rather sure it will.) I can't reproduce the problem.
I had the same problem (but with kdelibs-3.5.5-r10). Re-emerging kdelibs fixed the problem.
The libcrypto warning is harmless and unrelated to the problem. When you remove a library under the hood of a service kded will crash. Run `revdep-rebuild`. When this doesn't help, feel free to reopen.
This one is ancient and invalid, but since it was reported by me ... Eventually, after recompiling OpenSSL and kdelibs I-don't-know-how-many-times (up to 0.9.8g and 3.5.9-r1 respectively), I probably found a solution: compile OpenSSL without zlib support. Now it seems to work. See also backtraces and analysis at: http://bugs.kde.org/show_bug.cgi?id=160348
i, i have the same problem here, using dev-libs/openssl-0.9.8h-r1 and kde-base/kdelibs-3.5.9-r4 kded does indeed say : kdecore (KLibLoader): WARNING: KLibrary: /usr/lib64/libcrypto.so.0.9.8: undefined symbol: PKCS7_content_free but it doesn't crash there.

According to some googling I've made, it seems some people do have this problem, on different distribution (ubuntu,gentoo), but those all are isolated case. Don't know what to do, but this is really annoying : without kded running, no more coockies, no more password for kmail and such... The system is quickly not usable.
I can confirm that using USE=-zlib emerge --oneshot openssl fixed the problem here. Not sure about what i loose here, but it works. it prints those message, althought this doesn't seem to prevent it from working : kdecore (KLibLoader): WARNING: KLibrary: /usr/lib64/libcrypto.so.0.9.8: undefined symbol: PKCS7_content_free kdecore (KLibLoader): WARNING: KLibrary: /usr/lib64/libcrypto.so.0.9.8: undefined symbol: OpenSSL_add_all_algorithms kdecore (KLibLoader): WARNING: KLibrary: /usr/lib64/libcrypto.so.0.9.8: undefined symbol: OPENSSL_add_all_algorithms kdecore (KLibLoader): WARNING: KLibrary: /usr/lib64/libcrypto.so.0.9.8: undefined symbol: OpenSSL_add_all_algorithms_conf
