Hi,

It may have to do with not correctly finding the "libnssckbi.so" share
library, which is from NSS.  Here's what tipped me to it, in strace
output:

It never resolves libnssckbi.so.

LibreOffice attempts to load this library in
xmlsecurity/source/xmlsec/nss/nssinitializer.cxx, in the
'nsscrypto_initialize' procedure.

The library appears to be dynamically loaded via SECMOD_LoadUserModule.
Perhaps we can patch 'OUString rootModule("libnssckbi"
SAL_DLLEXTENSION)' to its full name.  Some more output, after building
libreoffice with "--enable-sal-log" and setting the 'SAL_LOG=+INFO'
environment variable:

So it seems to cause an error, which is apparently ignored.
