What steps will reproduce the problem?
I can arrange for you to get my open source code that exhibits this problem.

What version of the product are you using? On what operating system?
1.6.0 on Android 2.2

Thanks for the issue. 

Can you please send me some code that exhibits this problem or some more 
information? How often does this happen to you, is it under certain conditions?

I think this only happens if you specify a solo.goBack() too many so that you 
actually exit your app and then try to searchText() wrongfully. I'll try and 
see if I can create some minimal sample code that exhibits this. Downloading my 
project and its dependencies might be a bit much. Though you can find it at 
https://code.launchpad.net/~pjv/collectionista/tests. Should be revision 14 (or 
15) with some small changes (try inserting goBack()'s). You will also need the 
other trunks and dependencies.

I certainly don't always see this as a real exception. I think when this 
happens still INSIDE the app, you just get a comparable stacktrace, but WITHIN 
junit, as it should.

For instance, now I see (but within Junit, so ok):

So the last NullPointerException you have posted happened while still being in 
the application? A special scenario to make it happen?

I will make a change in the next release so that this problem is avoided. 
Thanks for pointing it out.

Exactly, the stacktrace from comment #3 is benign. It's the thing you want to 
see in jUnit if your program or test code is wrong. The stacktrace from the 
original post is not, it was retrieved through logcat.

I've been trying to get back the code that exhibited the problem, both in my 
fullproject, as in a small sample project, but have been unsuccessful. However 
at the time I could reproduce this 100% with that code. Sorry, I should have 
made a commit at that moment. Can you do anything useful with the stack trace 
by itself and the context of my code?

Yes this problem will be fixed in the next release. I know exactly why it 
happens, thanks for submitting this issue.
