I've tested this (with python and guile enabled) on:
- openSUSE Tumbleweed x86_64, where I did see FAIL before, and
   this series fixes it
- openSUSE Leap 15.4 x86_64
No problems found.

FWIW, I ran into this when applying:
...
$ git am ~/patches/grouped/eml/*
Applying: Introduce gdb_exception_forced_quit
Applying: Handle gdb SIGTERM by throwing / catching gdb_exception_force_quit
.git/rebase-apply/patch:37: indent with spaces.
         {
warning: 1 line adds whitespace errors.
Applying: Catch gdb_exception_error instead of gdb_exception (in many 
places)
Applying: Python QUIT processing updates
Applying: Guile QUIT processing updates
Applying: Call quit_force for gdb_exception_forced_quit in 
safe_execute_command
Applying: QUIT processing w/ explicit throw for gdb_exception_forced_quit

         throw;

         {

         {
warning: 3 lines add whitespace errors.
Applying: Forced quit cases handled by resetting sync_quit_force_run
.git/rebase-apply/patch:41: indent with spaces.
          to newline, so, for this case,  reset the quit flag for
warning: 1 line adds whitespace errors.
...

Thanks,
