If I start a flick and I press the back button while the Map is still flicking, it crashes. But it also crashes sometimes when the flick has finished so I can't simply test that flick is finished before doing the pagestack.pop():<br><br><font style="font-size: 10pt;" size="2">Program received signal SIGSEGV, Segmentation fault.</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">QString::lastIndexOf (this=0x4, ch=..., from=-1, cs=Qt::CaseSensitive) at tools/qstring.cpp:2727</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">2727 tools/qstring.cpp: No such file or directory.</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">(gdb) backtrace</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">#0 QString::lastIndexOf (this=0x4, ch=..., from=-1, cs=Qt::CaseSensitive) at tools/qstring.cpp:2727</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">#1 0x40089bf0 in QGeoTileCache::~QGeoTileCache (this=0x400a750c, __in_chrg=<optimized out>) at maps/qgeotilecache.cpp:202</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">#2 0x4008a06c in QGeoTileCache::~QGeoTileCache (this=0x2ad71fd0, __in_chrg=<optimized out>) at maps/qgeotilecache.cpp:208</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">#3 0x4007ad98 in QGeoTiledMappingManagerEnginePrivate::~QGeoTiledMappingManagerEnginePrivate (this=0x2a2b6b10, __in_chrg=<optimized out>)</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2"> at maps/qgeotiledmappingmanagerengine.cpp:328</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">#4 0x4007aefc in QGeoTiledMappingManagerEngine::~QGeoTiledMappingManagerEngine (this=0x2a4d5a68, __in_chrg=<optimized out>) at maps/qgeotiledmappingmanagerengine.cpp:68</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">#5 0x47ca43b0 in QGeoTiledMappingManagerEngineNokia::~QGeoTiledMappingManagerEngineNokia (this=0x2a4d5a68, __in_chrg=<optimized out>)</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2"> at qgeotiledmappingmanagerengine_nokia.cpp:139</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">#6 0x47ca43fc in QGeoTiledMappingManagerEngineNokia::~QGeoTiledMappingManagerEngineNokia (this=0x2a4d5a68, __in_chrg=<optimized out>)</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2"> at qgeotiledmappingmanagerengine_nokia.cpp:139</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">#7 0x4007a210 in ~QGeoMappingManagerPrivate (this=0x2a84d6c0, __in_chrg=<optimized out>) at maps/qgeomappingmanager.cpp:190</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">#8 QGeoMappingManager::~QGeoMappingManager (this=0x2a51a010, __in_chrg=<optimized out>) at maps/qgeomappingmanager.cpp:96</font><font style="font-size: 10pt;" size="2"><br></font><font style="font-size: 10pt;" size="2">#9 0x4007a244 in QGeoMappingManager::~QGeoMappingManager (this=0x2a51a010, __in_chrg=<optimized out>) at maps/qgeomappingmanager.cpp:97</font><br><br><br>For the second, I have a SilicaListView with images in the sections.
