Crashes QGIS or corrupts data: Copied to github as #:11714


At several places in the plugins code, the activated () signal of the QAction class is used to signal the plugin it has been activated. This is wrong : this signal has disappeared from Qt4 and if QT4 is not compiled with the Qt3 backward compatibility, it is simply non existent, so no plugin can be called at all.

Please replace activated () by triggered () (It fixes the bug).

The same bug exists in various python plugins. It should be notified to plugin writers and maybe added on the Wiki
