Ahh, right.

I just dusted off my FC6 VM, installed PostgreSQL 8.2.4 and wxGTK 2.8.4,
both from source and SVN-trunk builds and runs perfectly (all bar a
minor toolbar button sizing issue that you wouldn't notice unless you
stared at pgAdmin as much as I do!!).

The pgAdmin function it's dying in is this:

bool isPgApp(const wxString &app)
{
if (!wxFile::Exists(app))
return false;

wxArrayString output;

wxExecute(app + wxT(" --version"), output, 0);

if (output[0].Contains(wxT("PostgreSQL")))
return true;

return false;
}

Given that it appears to be bailing in wxStringBase::find, I'd guess
that's the "if (output[0].Contains(wxT("PostgreSQL")))" line. There's
nothing wrong with that, so I'd have to guess there's a problem with
your wx build.

I agree with your idea - grab wxGTK 2.8.4 and try rebuilding it from
scratch (there's a script in xtra/wx-build in the pgAdmin source tree to
build all the different combinations of build that we support).
