formlayout: TypeError: QComboBox.addItems(QStringList): argument 1 has unexpected type 'list'

[mdboom]

Clicking on the "edit curves [sic] line and axes parameters" button on a figure generated by the plot() command in the qt4 backend raises this error:

In [1]: plot(np.arange(10))
Out[1]: [<matplotlib.lines.Line2D at 0x3199b50>]

In [2]: Traceback (most recent call last):

Histogram plots don't seem to have this problem. Editing the figure generated by hist(np.arange(10)) works fine.

This may have been triggered by 97c58d2 in #693. On second thought, that seems unlikely.

Sounds like something similar was previously reported here:

http://code.google.com/p/formlayout/issues/detail?id=4

This is with git master mpl, Qt 4.7.2, and PyQt4 4.8.3-2 on Ubuntu 11.04.

@mspacek: Can you confirm this resolves your issue.

Yes, that fixed it. Thanks!
