You are right.  I also ended up trying with “wget --save-headers” after
sending the bug report and noticed the offending header like you did:

Right.  I worked around this in guile-debbugs simply by replacing the
Content-Type header parser with one that lacks the check for the unique
“=” in the string part.

bug#32580: Setting variables %load-should-autocompile and GUILE_AUTO_COMPILE in ~/.guile doesn't prevent compiling

[seamus phenetols]

I'm new to guile and scheme.  I compiled 2.2.4 from source yesterday.
I wish to silence the auto-compile chatter, other than real warnings and errors
while testing my programs.  There seems to be no way to do it, so I looked
for a way to disable auto-compile in ~/.guile configuration file.  No luck so 
far,
but the variables %load-should-autocompile and GUILE_AUTO_COMPILE
seem promising.  Sadly, they don't seem to prevent auto-compile when
set within ~/.guile.

Below is an excerpt of my shell session to demonstrate.  In case it may be
poorly formatted, I could make  a web paste for easy viewing.
