[gnutls-devel] Revoked certificate count in CRL is capped at 34

I am working on a small project where I'm planning to do periodic CRL generation with GNUTLS from concatenated to-be-revoked-certificates. The CRL is generated as per the guide:
certtool --generate-crl --load-ca-privkey $CAPRIVKEY \
--load-ca-certificate $CACERT \
--load-certificate syssec-int.pem \
--template infosec-vpn-int.cfg \
The template is really simple:
# Options for generating a CRL
# next CRL update will be in 43 days
crl_next_update = 43
# this is the 7th CRL by this CA
crl_number = 7
When running the command this is what I see in the debug:
Setting log level to 900
Generating a signed CRL...
Loading certificate list...

Loaded 34 certificates.

X.509 Certificate Revocation List Information:
Issued: Wed Aug 12 15:39:16 UTC 2015
Next at: Thu Sep 24 15:39:16 UTC 2015
Authority Key Identifier (not critical):
CRL Number (not critical): 07
Revoked certificates (34):
certtool -i --infile syssec-int.pem | grep -i subject: | wc -l
Using stock certtool on Debian Wheezy:
certtool (GnuTLS) 2.12.20
Packaged by Debian (2.12.20-8+deb7u3)
And on Debian Jessie:
I know the Debian supplied versions are always lagging behind, but I haven't seen any open/fixed bugs with this issue.
One thing that might be important to mention is that the certificates have been issued by openssl originally, but as the debug doesn't say anything if it had problems with the formatting or anything I assume this is not a problem.
Also, as far as I learned, there should be no reason of any capping, as I read there could be CRLs with size reaching several MBs so I am suspecting that there is either a bug with files having too many certs in them or something is missing from the documentation.
Looking forward to hearing from you,
