EXCEPTION: 11DbException       
Db::get: Cannot allocate memory       
namecoin in Runaway exception

Edit: however I built the namecoind in the same branch and launches ok (after namecoin-qt did the rescan?) so maybe namecoin-qt crashed at end of rescan ...

I see the same error on Debian Wheezy. After the crash, I can start namecoind-qt (in my case) fine, but every name_show returns an error (code -4, could not read name from DB - the same one one gets for non-existing names). The same things happen if I manually delete nameindexfull.dat and force a rescan that way.

This commit is not working anymore with latest patch from namecoin-qt ("An improved patch").
You need to apply this patch too :

after https://github.com/cjdelisle/namecoin-q ... 63265799f6 & https://github.com/cjdelisle/namecoin-q ... e003054b1c

The code to fix the bug on the namecoin/master repository is available there and will be merged in the official repo when ready :

I've just updated to the current status of namecoin-qt in git, and now everything seems to work for me. I'll update the version on nameid.org now, and test that there, too.
