9-patch not working

Question

I'm having strange issues with 9-patch png's on Android. It already fails in Eclipse visual editor, no matter which target I use (tried several between 7 and 14). The error log shows the message main.xml: Index: 0, Size: 0 The exception behind is:

The 9-patch was created with the draw9patch-tool included in the SDK. I have this issues with all the images I use in this project. I already used 9-patch before in other projects without problems and thus assume there's something specific to the format of my current png's. Maybe the used Photoshop of the designer creates png's which result in invalid 9-patches. Does anybody have an idea what's the issue here?
