I work with QGIS 2.4 on windows 7.
The problem occurs when I work on a layer and save it many times. After a random number of saves, pressing the save button once more causes QGIS to freeze, all processor being used for more than two minutes. Exiting the edit mode for the layer also causes that behaviour.
The only solution to the problem is relaunching qgis. Saving the project does not cause a freeze, but clearing the actual project does. And with that button the freeze will not recover, so I have to kill QGIS.
Has anyone encountered the same issue, or has any idea about it ?
