If apparent AddPropertyStub request for non-existent property, it should be NS_ERROR_XPC_CANT_CREATE_WN, or NS_ERROR_XPC_CANT_ADD_PROP_TO_WRAPPED_NATIVE, or one like NS_ERROR_XPC_CANT_CREATE_PROP_ON_WN. If XPC_WN_OnlyIWrite_SetPropertyStub is called both when "setting of existent property" and "stting non-existent property" case, they should be separated to NS_ERROR_XPC_CANT_CREATE_WN(or NS_ERROR_XPC_CANT_ADD_PROP_TO_WRAPPED_NATIVE or one like NS_ERROR_XPC_CANT_CREATE_PROP_ON_WN) case and NS_ERROR_XPC_CANT_MODIFY_PROP_ON_WN case. > http://mxr.mozilla.org/comm-central/source/mozilla/xpcom/base/ErrorList.h#608 > 608 ERROR(NS_ERROR_XPC_CANT_CREATE_WN, FAILURE(25)), > http://mxr.mozilla.org/comm-central/source/mozilla/xpcom/base/ErrorList.h#629 > 629 ERROR(NS_ERROR_XPC_CANT_ADD_PROP_TO_WRAPPED_NATIVE, FAILURE(46)), > http://mxr.mozilla.org/comm-central/source/mozilla/xpcom/base/ErrorList.h#635 > 635 ERROR(NS_ERROR_XPC_CANT_MODIFY_PROP_ON_WN, FAILURE(52)), -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/605513 Title: Get uncaught exception when populating a form in FireFox 3.6 Status in The Mozilla Firefox Browser: Confirmed Status in “firefox” package in Ubuntu: Triaged Bug description: Binary package hint: firefox When populating an input field on a form in Firefox (Linux or Windows) where I select or just pass the mouse over one of the historical suggestions that drops down while inputting, I receive the following error: Error: uncaught exception: [Exception...
