I’m running Ubuntu Lucid (32 bit), all packages up to date. I had run bitcoin 0.2 previously, and just downloaded 0.3. I ran bitcoind and I got:

bitcoin: main.cpp:823: unsigned int GetNextWorkRequired(const CBlockIndex*): Assertion `pindexFirst’ failed. Aborted

So I ran the bitcoin GUI, and it came up and showed my existing coins, but quickly gave me the same error and died. Then I went back and ran the 0.2 GUI again and I get:

bitcoin: main.cpp:743: unsigned int GetNextWorkRequired(const CBlockIndex*): Assertion `pindexFirst’ failed. Aborted

Has my db got corrupted? Do I have a broken dependancy?

I tried to build 0.3 from source but got many errors, probably missing some *-dev packages. Will look at that more later.

That’s the first time I’ve seen this error.

How many blocks do you have? (in the status bar)

You should move your blk*.dat files (in ~/.bitcoin) to another directory and let it start over downloading the block chain again.  If you don’t mind, could you keep the old blk*.dat files for a little while in case I need to look at them?

I have 58464 blocks… haven’t run the software in awhile

Moved the block files… it’s working through them all again. My coins disappeared, but I assume they’ll come back when it’s up to current?

Right, they’ll re-appear when it’s finished downloading all the blocks.

I just wanted to let you know that i experienced the exact same problem on Ubuntu 10.04.3 64-bit using the current version of the Bitcoin client. The block where it crashes is 130670.
