I just installed matplotlib 0.87.5 and numpy 1.0 from source on my
Debian "sarge" (stable release) system. (I chose those versions
because they're the ones currently included in the testing "etch"
release.) Everything I've tried has worked *except* the ylabel()
command. Whenever a plot containing a ylabel is rendered (on the
screen with show() or figure(), or non-interactively with savefig()),
python exits with the error
Floating exception
This does not happen if the ylabel() command is omitted, and there is
no problem with xlabel(), so I assume the issue is rotating the text
for the y axis label.
Simple example:

Anyone have experience with this and care to point me towards the
solution to such a problem?
Thanks,
