I don't think it is realistic to debug this remotely via bugzilla comments, but
let me give this a try once:

The interesting part from your backtrace is this:

> Program received signal SIGSEGV, Segmentation fault.
> 0x00007fffeb6d82b0 in SECKEY_GetPublicKeyType () from /home/gabor/src/core/instdir/program/libnss3.so
> #0  0x00007fffeb6d82b0 in SECKEY_GetPublicKeyType () from /home/gabor/src/core/instdir/program/libnss3.so
> #1  0x00007fffae5e49b3 in xmlSecNssKeyDataEcdsaGetType (data=0x7683fb0) at pkikeys.c:1463

xmlSecNssKeyDataEcdsaGetType() is "my" code in xmlsec;
SECKEY_GetPublicKeyType() gets called just to assert that you you ask the "is
this a public or a private+public key?" question with this function for an
ecdsa key. Does it make any difference if you comment out that second assert?
(Edit workdir/UnpackedTarball/xmlsec/src/nss/pkikeys.c:1463, i.e. comment out
that line, make build-nocheck).

I expect this is some corruption and it'll just crash a bit later at a
different place if getting the type of a key causes a crash, but it is worth a
try.
