Try hard coding the full path to dvipng from the command line and in
texmanager to make sure you are using the version you think you are.
Also, flush the tex cache.

Find this bit of code in texmanager

            vers = self.get_dvipng_version()
            #print 'dvipng version', vers
            if vers<'1.6':
                # hack the alpha channel as described in comment above
                alpha = sqrt(1-X[:,:,0])
            else:
                alpha = X[:,:,-1]

print the dvipng version in texmanager.  Also, see which part of the
conditional you are executing, and then manually try forcing both with 


            if 1:
                # hack the alpha channel as described in comment above
                alpha = sqrt(1-X[:,:,0])
            else:
                alpha = X[:,:,-1]


and

            if 0:
                # hack the alpha channel as described in comment above
                alpha = sqrt(1-X[:,:,0])
            else:
                alpha = X[:,:,-1]


Make sure you flush the tex cache and rerun matplotlib from the shell
(not ipython) with each test.
