We have roundup running as an issuetracker on a netbsd 
machine.

It worked fine, but this morning for no apparent reason it 
gives the following error on any modification to an issue:


error: Error -5 while decompressing data Python 2.2.3
/usr/pkg/bin/python2.2 

A problem occurred while running a Python script. Here is 
the sequence of function calls leading up to the error, 
with the most recent (innermost) call first. The 
exception attributes are:

      __init__ = <bound method error.__init__ of

      __module__ = 'zlib' 
      __str__ = <bound method error.__str__ of 
<zlib.error instance>> 
      args = ('Error -5 while decompressing data',)
