Bug report

Bug summary

When I use the Axes.text () method with rotation='vertical', and call it a sufficient number of times (greater than 7 times in the example below), the resulting figure is rotated by 90 degrees if saved to an eps file. The plot is normal (unrotated) if any of the following are satisfied: Axes.text() is called less than 7 times; or the plot is saved directly to a png file; or the calls to Axes.text() do not specify rotation='vertical'.

Code for reproduction

import matplotlib.pyplot as pl

f = pl.figure (figsize=(7,5))
ax = f.add_axes ([0.15,0.15,0.8,0.8])
ax.set_ylim (0., 1.)
ax.set_xlim (0., 1.)

ntext = 8 # this is the minimum number of calls to get rotation
ytext = 0.5
for i in range (ntext) :
    xtext = (xmax / ntext) * i
    n = 'test{}'.format (i)
    ax.text (xtext, ytext, n, rotation='vertical')

f.savefig ('test.eps')

Actual outcome

The gzipped eps file is attached, as is a png created from the eps using ImageMagick convert.
test.eps.gz

Expected outcome

An unrotated plot, regardless of the number of times Axes.text() is called.
