H A D | qcow2.h | f50f88b9 Fri Dec 07 17:08:46 GMT 2012 Kevin Wolf <kwolf@redhat.com> qcow2: Allocate l2meta only for cluster allocations
Even for writes to already allocated clusters, an l2meta is allocated, though it stays effectively unused. After this patch, only allocating requests still have one. Each l2meta now describes an in-flight request that writes to clusters that are not yet hooked up in the L2 table.

One of the recent refactoring patches (commit f50f88b9) didn't take care to initialise l2meta properly, so with zero-length writes, which don't even enter the write loop, qemu just segfaulted.
