Hashing only happens on hash or set keys. So find where the akey parameter was passed from: > #1 0x000000000044c2a3 in QHash<QString, QHashDummyValue>::findNode > (this=0x87eac0, akey=..., ahp=0x0) at /usr/include/QtCore/qhash.h:875 > #2 0x0000000000477b92 in QHash<QString, QHashDummyValue>::contains > (this=0x87eac0, akey=...) at /usr/include/QtCore/qhash.h:867 > #3 0x0000000000475797 in QSet<QString>::contains (this=0x87eac0, > value=...) at /usr/include/QtCore/qset.h:86 > #4 0x000000000045cc7e in QgsProjectParser::mapLayerFromStyle > (this=0x87e9e0, lName=..., styleName=..., useCache=true) at > /root/qgis/qgis-2.0.1/src/mapserver/qgsprojectparser.cpp:1365 At this point in the code, you made a call to contains(). The string you passed is not valid. You probably have dangling pointers or other problems if you managed to get an invalid QString. You may want to try running your application in valgrind. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
