General notes:

/usr/lib/qubes/qubes-rpc-multiplexer starts with #!/bin/sh, so should be posix shell. But it calls /tmp/qubes-session-env (via -l?) which calls declare, which isn't posix. Replacing those declare -x with export seems to fix the issue.

I can confim "fixing" the issue by replacing declare -x with export in /tmp/qubes-session-env. Though, I couldn't find out where the qubes-session-env-File gets generated in order to fix this.
