Using Proguard with Android without obfuscation

I am getting an error "Conversion to Dalvik format failed with error 1" when using the -dontobfuscate flag. Otherwise my app exports fine. I don't want to obfuscate because I am using BugSense for error tracking and they charge $99 a month if you need to de-obfuscate your stack traces. I still want to get the file size and optimization benefits of proguard.

If I comment out -dontobfuscate every thing works great. Except for the unreadable stack traces.

my progaurd.cfg file:

-dontobfuscate
-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService

-keepclasseswithmembernames class * {
    native <methods>;
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

I will also accept an answer that points me in the right direction. Is there a log file I should be looking at?

Add !code/allocation/variable is workaround for ProGuard bug when -dontobfuscate is set to your -optimizations

For example

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*,!code/allocation/variable
