The patch below from our friends at Red Hat may address the issue. Looks someone thought Zoneminder should use libgcrypt instead of openssl or gnutls.
This patch will need slight modification to work with the current 1.26 source tree. I'll create a new branch and try it next time I have a moment. I'm at work now (Internet break).

Well I got the patch to compile cleanly, but it did not resolve the issue. However, it did help me identify where exactly things were going wrong. zm_user.cpp was the culprit. I noticed that auth_md5 was exactly twice as big as it was supposed to be.
Changed line 199 from:
size_t md5len = 32;
to:
size_t md5len = 16;
and this seemed to resolve the issue on my centos vm.
I want to do some additional test (test on ubuntu for one) tomorrow and then I'll submit a pull request.

I'm still able to replicate these conditions / failure mode in Debian variant Raspbian running 1.29.0 fresh install - I'm not sure if the cause is the same but the workaround is.

@george-viaud Can you be clearer which workaround? The change to md5len?

Sorry about the ambiguity.
I disabled the hash options in the configuration and the problem ceased - (I think this has the end effect of going around the hashing code all-together).

Playing with this again today. Observation:
Browsing to /zm/cgi-bin/zms while hash is enabled results in a Internal Server Error and the following in the apache2 error.log file:
[cgi:error] [pid 1722] [client x.x.x.x:xxxxxx] End of script output before headers: zms

I'm closing this again as this thread has gone stale.
I haven't seen this on my pi's, but if someone still has this issue and has new, relevant data then please create a new issue.

I also experience this error when hash is enabled in zoneminder 1.34.16, when AUTH_RELAY is none, zms works fine.

Probably your timezones are incorrectly set (this is the #1 reason why this fails.) Go actually look in your logs. Turn on debug. Look again.
