OpenLayers plugin and QGIS 1.9: Error after install

After I installed the OpenLayers Plugin (1.0.0) on my QGIS 1.9 this error appears:

Konnte Erweiterung openlayers_plugin nicht laden wegen eines Fehler beim Aufruf seiner initGui()-Methode

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/qgis/utils.py", line 198, in startPlugin

Any ideas?

Answer

As said to the post above, recently some methods in API have been removed so, if you can not wait for the next version what you have to do is replace this file into

{home}/.qgis/python/plugins/openlayers_plugin

the patch works both for 1.8 version that master version.
