Ok, I finally managed to get a crash log, and it wasn't related to the map view at all.
The crash happens when calling XDocument.Load() with a URL. This is the crash log: 2012-04-30 12:33:19 Exception: Cannot cast from source type to destination type. 2012-04-30 12:33:19 at MonoTouch.Foundation.NSArray.ArrayFromHandle[NSDictionary] (IntPtr handle) [0x00000] in <filename unknown>:0 at MonoTouch.CoreFoundation.CFNetwork.GetProxiesForURL (MonoTouch.Foundation.NSUrl url, MonoTouch.CoreFoundation.CFProxySettings proxySettings) [0x00000] in <filename unknown>:0 at MonoTouch.CoreFoundation.CFNetwork.GetProxiesForUri (System.Uri uri, MonoTouch.CoreFoundation.CFProxySettings proxySettings) [0x00000] in <filename unknown>:0 at MonoTouch.CoreFoundation.CFNetwork+CFWebProxy.GetProxy (System.Uri targetUri) [0x00000] in <filename unknown>:0 at MonoTouch.CoreFoundation.CFNetwork+CFWebProxy.IsBypassed (System.Uri targetUri) [0x00000] in <filename unknown>:0 at System.Net.ServicePointManager.FindServicePoint (System.Uri address, IWebProxy proxy) [0x00000] in <filename unknown>:0 at System.Net.HttpWebRequest.GetServicePoint () [0x00000] in <filename unknown>:0 at System.Net.HttpWebRequest.BeginGetResponse (System.AsyncCallback callback, System.Object state) [0x00000] in <filename unknown>:0 at System.Net.HttpWebRequest.GetResponse () [0x00000] in <filename unknown>:0 at System.Xml.XmlUrlResolver.GetEntity (System.Uri absoluteUri, System.String role, System.Type ofObjectToReturn) [0x00000] in <filename unknown>:0 at Mono.Xml2.XmlTextReader.GetStreamFromUrl (System.String url, System.String& absoluteUriString) [0x00000] in <filename unknown>:0 at Mono.Xml2.XmlTextReader..ctor (Boolean dummy, System.Xml.XmlResolver resolver, System.String url, XmlNodeType fragType, System.Xml.XmlParserContext context) [0x00000] in <filename unknown>:0 at System.Xml.XmlTextReader..ctor (Boolean dummy, System.Xml.XmlResolver resolver, System.String url, XmlNodeType fragType, System.Xml.XmlParserContext context) [0x00000] in <filename unknown>:0 at System.Xml.XmlReader.Create (System.String url, System.Xml.XmlReaderSettings settings, System.Xml.XmlParserContext context) [0x00000] in <filename unknown>:0 at System.Xml.XmlReader.Create (System.String url, System.Xml.XmlReaderSettings settings) [0x00000] in <filename unknown>:0 at System.Xml.Linq.XDocument.Load (System.String uri, LoadOptions options) [0x00000] in <filename unknown>:0 at System.Xml.Linq.XDocument.Load (System.String uri) [0x00000] in <filename unknown>:0 at Proxio.WebService.GetDropdownValues[PropertyType] (System.String serviceName) [0x00000] in <filename unknown>:0 at Proxio.WebService.GetPropertyTypes () [0x00000] in <filename unknown>:0 at Proxio.WebService+<Async>c__AnonStorey0`1[System.Collections.Generic.IEnumerable`1[Proxio.PropertyType]].<>m__3 () [0x00000] in <filename unknown>:0 at System.Threading.Thread.StartInternal () [0x00000] in <filename unknown>:0 -- View this message in context: http://monotouch.2284126.n4.nabble.com/MKMapView-crashing-on-all-my-customer-s-iPads-runs-fine-on-ours-tp4590869p4598042.html Sent from the MonoTouch mailing list archive at Nabble.com. _______________________________________________ MonoTouch mailing list [email protected] http://lists.ximian.com/mailman/listinfo/monotouch
