Hi,<br>I'm trying to use the "dissolve" operation (vector -> geoprocessing tools -> dissolve) on different vectors (tested also the one in the qgis sample dataset), but QGIS always crashes. Tested with both 1.4 and trunk under Ubuntu 9.10.<br>
<br>Here are the terminal messages<br><br>--------------------------------------<br>Warning: QObject::connect: Incompatible sender/receiver arguments<br> QgsProject::writeProject(<div id=":ey" class="ii gt">QDomDocument&) --> QgisApp::projectChanged(QDomDocument)<br>
