IllegalStateException in Editor#newOutputStream()

[bergstr11]

I am using the latest code from github and am seeing an IllegalStateException from the following code in DiskLruCache.java, lines 770 - 772:

if (entry.currentEditor != this) {
throw new IllegalStateException();
}

this happens quite rarely (seen it for the first time after several months, with 200 people using my app), and I have no indication what may cause it. No comments, no exception message. Thats why I choose this path of creating an issue. I'd appreciate any help, and would also suggest better error reporting
