[rdiff-backup-users] Bailout on broken rdiff-backup-data/ dir

[Ingo Ruhnke]

I am using:

$ rdiff-backup --version
rdiff-backup 0.13.3

I am not 100% sure how the rdiff-backup-data directory got broken, but
what happened was this. I was running rdiff-backup on an unregular
basis, normally a few times a week. Then one day my hd or the IDE bus
got crazy:

----
...
blk: queue f084ef3c, I/O limit 4095Mb (mask 0xffffffff)
hdg: dma_timer_expiry: dma status == 0x20
hdg: timeout waiting for DMA
...
----

The hd's itself worked fine again after a reboot, but reiserfs got
broken and required a --rebuild-tree. Ok, so I did that and everything
was back to normal. The filesystem containing the rdiff-backup data
should not have been mounted while this has happened, but I am not
100% sure on that, but anyway, it got broken too and now I am being
unable to backup, the rdiff-backup output looks like below. Is there
any way I can let rdiff-backup fixup the broken tree or do I have to
completly 'rm' it and start from scratch (not such a good idea, since
I might need some of the data in there, due to the --rebuild-tree
which broke some files):
