The code below prints the right thing for me. The last conversion
to cp850 is there to make the Swedish letters look right at a
Windows command prompt, since that still uses an ancient DOS encoding.
You don't want that if you print in a normal Windows context or run
it in a better operating system. I'm using Python 2.2.2.

--------
from email.Header import decode_header

raw_text = 
"""=?iso-8859-1?Q?Hej=2C_tack_f=F6r_bra_team_work_p=E5_ndc5_i_fredags_efterm?=
      =?iso-8859-1?Q?iddag!_/Rolf?="""

header = decode_header(raw_text)

result = u''

for text, encoding in header:
     result += text.decode(encoding)

print result.encode('cp850')

As you see I'm not using the safety nets that Michal showed. They
are not needed for this particular example, but it's probably good
to have something like that. I think it's enough with just the try
block though, it will catch empty encodings, and in general I try
to avoid unqualified except clauses. I guess I'd use (untested):

for text, encoding in header:
     try:
         result += text.decode(encoding)
     except (UnicodeError, ValueError):
         result += text
