guile self-tests fail in v.2.5?

Hi Ludovic,

On the master trunk there has been some heavy internal changes recently,
but no incompatible API changes as far as I understand, and now the
guile self-tests fails:

make[3]: Entering directory `/home/jas/src/gnutls/guile/tests'
guile: uncaught throw to gnutls-error: (#<gnutls-error-enum The Diffie Hellman prime sent by the server
is not acceptable (not long enough).> handshake)
make[3]: *** [check-TESTS] Interrupt

Actually I need to ctrl-c it to cancel it.

Do you have any idea?  How would I debug this, anyway?  I am a bit at a
loss when running into any guile problem.

Thanks,
/Simon
