SimpleXML falla en Lenovo P90

Tenemos problemas con el uso de SimpleXml y Proguards obfuscation en uno (por ahora sólo encontramos uno) dispositivo específico. Es Lenovo P90.

En todos los demás dispositivos, la aplicación funciona bien hasta ahora. También cuando apago la ofuscación, la aplicación funciona bien.

Estas son algunas partes importantes de la configuración del proyecto / build SimpleXml import:

 compile('com.squareup.retrofit:converter-simplexml:1.9.0') { exclude module: 'stax' exclude module: 'stax-api' exclude module: 'xpp3' }

Configuración de Proguard para simplexml (busqué más reglas pero nada funcionó hasta ahora):

 # simplexml -dontwarn org.simpleframework.xml.stream.StreamProvider -dontwarn org.simpleframework.xml.stream.StreamReader* -keep class org.simpleframework.xml.core.**{ *; }
