still a bug with getpwuid_r [was: Re: 1.1.14 and a lot of core dumps]

[Trog <trog gtk org>]

It now looks like this in the CVS:

 guint bufsize = 64;

I'm not convinced that this is correct. The buffer should be big
enough to hold the largest entry in /etc/passwd.

The Digital Unix man page states:

[Digital]  The minimum buffer size is 1024 bytes as defined for
            SIABUFSIZ in /usr/include/sia.h.

As 64 < 1024 we appear to have a problem.
