Assertion `m_firstLoaded != -1' failed

[GoogleCodeExporter]

I had the assertion below trigger twice over the evening. Not sure how to 
reproduce, the data (contraction hierarchies and gps grid) is always the same, 
the queries (coordinates) always different.

MoNavD: blockcache.h:109: void BlockCache<Block>::useBlock(int) [with Block = 
CompressedGraph::Block]: Assertion `m_firstLoaded != -1' failed.

Program received signal SIGABRT, Aborted.
