It seems to be a fairly common issue: http://code.google.com/p/android/issues/detail?id=830

A workaround is to export an unsigned package and sign it manually with signapk.jar

Comment 26 by lucasiturbide, Apr 14, 2010 Hi everybody. I have solved this in my project by signing the APK with the debugkey and the jarsigner tool provided by android tools.

Just execute this:

 jarsigner -verbose -keystore <userhome>/.android/debug.keystore <package.apk> androiddebugkey

and you will have your nice fresh and working apk for debugging only purpose. Remember you have to sign your APK with a valid signature to publish your application at the Market

The password for the debug key with the alias "androiddebugkey" is "android".
