Sometimes, when loading macnn.com, I get this output on the console:

ERROR: SQLite database failed to load from 
Cause - out of memory
(/OpenSource/WebCore/platform/sql/SQLiteDatabase.cpp:70 bool WebCore::SQLiteDatabase::open(const WTF::String&, bool))

This is coming out of geolocation code:

#0  WebCore::SQLiteDatabase::open (this=0x13739ad20, filename=@0x10bcc9008, forWebSQLDatabase=false) at /Volumes/InternalData/Development/webkit/OpenSource/WebCore/platform/sql/SQLiteDatabase.cpp:71

#5  0x000000010320ed57 in WebCore::GeolocationPositionCache::threadEntryPoint (object=0x10bcc8f10) at /Volumes/InternalData/Development/webkit/OpenSource/WebCore/page/GeolocationPositionCache.cpp:113
#6  0x0000000101a8d149 in WTF::threadEntryPoint (contextData=0x10bcbb0b0) at /Volumes/InternalData/Development/webkit/OpenSource/JavaScriptCore/wtf/Threading.cpp:65

filename is a null string.

So:
1. Why is getting window.geolocatiaon spawning a thread and trying to open a database?
2. Why is the database path empty?
3. Why is the SQL error so totally bogus?
