Summary0004973: SAML login segmentation fault
Description

Have configured sogo to authenticate through saml to a simplesamlphp backend. Accessing sogo redirects to idp login page and after correct login, idp redirects to SOGo/saml2-signon-post, where apache throws an error "Error reading from remote server".
Further looking in sogo.log, the error seems to be the termination of a child process with signal 11:
<0x0x56473396c310[WOWatchDogChild]> (terminated due to signal 11).
After installing *-debuginfo and running sogo inside gdb debugger (according to sogo how to debug guide) I get the same error on the web page, and gdb indicates a segmentation fault:

Feb 28 14:00:39 sogod [15937]: |SOGo| starting method 'GET' on uri '/SOGo/saml2-signon-post'
Feb 28 14:00:39 sogod [15937]: <0x0x5555558a4db0[SOGoCache]> Cache cleanup interval set every 300.000000 seconds
Feb 28 14:00:39 sogod [15937]: <0x0x5555558a4db0[SOGoCache]> Using host(s) 'localhost' as server(s)

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff4f4a7cf in objc_msg_lookup () from /lib64/libobjc.so.4

Also mentioning that the SAML IdP is configured with the attribute nameformat: urn:oasis:names:tc:SAML:2.0:attrname-format:uri and oid -> name conversion is being done, as indicated in the sogo configuration guide (settings for simplesamlphp).

Steps To Reproduce

Configure sogo with simplesamlphp auth source, exchange metadata, etc.
Access sogo, attempt to login with correct credentials when the IdP presents its login page.
Error shows up: Error reading from remote server; The proxy server could not handle the request GET /SOGo/saml2-signon-post.

Tagssaml, sogo
