Just so we're clear: you have a 0.6 database using anydbm 
that you've exported, then imported into 0.6 using mysql. Then 
upgrading to 0.7 results in the above error? 
 
Would you be willing to make the 0.6 export available to me so 
I can debug the problem? Contact me via my sourceforge email 
address (richard@users...)
