Root login leads to pam_getenvlist: NULL pam handle passed

[ltWolfik]

Hello. Some my PAM modules setup environment. Noticed that does not work on root logging by ssh and the following message appears in log:

authpriv.err dropbear[4612]: PAM pam_getenvlist: NULL pam handle passed

When logging by ssh to another user/shell - setting environment works ok. Any ideas?
